DRUGS & SUPPLEMENTS
1 INDICATIONS AND USAGE
Novastan Injection is a direct thrombin inhibitor indicated:
1.1 Heparin-Induced Thrombocytopenia
Novastan Injection is indicated for prophylaxis or treatment of thrombosis in adult patients with heparin-induced thrombocytopenia (HIT).
1.2 Percutaneous Coronary Intervention
Novastan Injection is indicated as an anticoagulant in adult patients with or at risk for HIT undergoing percutaneous coronary intervention (PCI).
2 DOSAGE AND ADMINISTRATION
Each 250 mL polyolefin bag contains 250 mg of Novastan ; and, as supplied, is ready for intravenous infusion. Dilution is not required.
Novastan Injection is a clear, colorless to pale yellow solution. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Do not use if the solution is cloudy, contains precipitates, or if the flip-off seal is not intact.
Heparin-Induced Thrombocytopenia (2.1)
The dose for heparin-induced thrombocytopenia without hepatic impairment is 2 mcg/kg/min administered as a continuous infusion (2.1)
Percutaneous Coronary Intervention (2.2)
The dose for patients with or at risk for heparin-induced thrombocytopenia undergoing percutaneous coronary intervention is started at 25 mcg/kg/min and a bolus of 350 mcg/kg administered via a large bore intravenous line over 3 to 5 minutes (2.2)
2.1 Dosing in Patients with Heparin-Induced Thrombocytopenia
Before administering Novastan Injection, discontinue heparin therapy and obtain a baseline aPTT. The recommended initial dose of Novastan Injection for adult patients without hepatic impairment is 2 mcg/kg/min, administered as a continuous infusion (see Table 1).
a with or without thrombosis
For use in HIT, therapy with Novastan Injection is monitored using the aPTT with a target range of 1.5 to 3 times the initial baseline value (not to exceed 100 seconds). Tests of anticoagulant effects (including the aPTT) typically attain steady-state levels within 1 to 3 hours following initiation of Novastan Injection. Check the aPTT 2 hours after initiation of therapy and after any dose change to confirm that the patient has attained the desired therapeutic range.
After the initiation of Novastan Injection, adjust the dose (not to exceed 10 mcg/kg/min) as necessary to obtain a steady-state aPTT in the target range [see Clinical Studies (14.1)].
2.2 Dosing in Patients Undergoing Percutaneous Coronary Intervention
Initiate an infusion of Novastan Injection at 25 mcg/kg/min and administer a bolus of 350 mcg/kg via a large bore intravenous line over 3 to 5 minutes. Check an activated clotting time (ACT) 5 to 10 minutes after the bolus dose is completed. The PCI procedure may proceed if the ACT is greater than 300 seconds.
If the ACT is less than 300 seconds, an additional intravenous bolus dose of 150 mcg/kg should be administered, the infusion dose increased to 30 mcg/kg/min, and the ACT checked 5 to 10 minutes later (see Table 2).
If the ACT is greater than 450 seconds, decrease the infusion rate to 15 mcg/kg/min, and check the ACT 5 to 10 minutes later (Table 3).
Continue titrating the dose until a therapeutic ACT (between 300 and 450 seconds) has been achieved; continue the same infusion rate for the duration of the PCI procedure.
In case of dissection, impending abrupt closure, thrombus formation during the procedure, or inability to achieve or maintain an ACT over 300 seconds, additional bolus doses of 150 mcg/kg may be administered and the infusion dose increased to 40 mcg/kg/min. Check the ACT after each additional bolus or change in the rate of infusion.
For use in PCI, therapy with Novastan Injection is monitored using ACT. Obtain ACTs before dosing, 5 to 10 minutes after bolus dosing, following adjustments in the infusion rate, and at the end of the PCI procedure. Obtain additional ACTs every 20 to 30 minutes during a prolonged procedure.
Continued Anticoagulation after PCI
If a patient requires anticoagulation after the procedure, Novastan Injection may be continued, but at a rate of 2 mcg/kg/min and adjusted as needed to maintain the aPTT in the desired range [see Dosage and Administration (2.1)].
2.3 Dosing in Patients with Hepatic Impairment
For adult patients with HIT and moderate or severe hepatic impairment (based on Child-Pugh classification), an initial dose of 0.5 mcg/kg/min is recommended, based on the approximately 4-fold decrease in Novastan clearance relative to those with normal hepatic function. Monitor the aPTT closely, and adjust the dosage as clinically indicated.
Achievement of steady-state aPTT levels may take longer and require more dose adjustments in patients with hepatic impairment compared to patients with normal hepatic function.
For patients with hepatic impairment undergoing PCI and who have HIT or are at risk for HIT, carefully titrate Novastan Injection until the desired level of anticoagulation is achieved. Use of Novastan Injection in PCI patients with clinically significant hepatic disease or AST/ALT levels greater than or equal to 3 times the upper limit of normal should be avoided [see Warnings and Precautions (5.2)].
2.4 Dosing in Pediatric Patients with Heparin-Induced Thrombocytopenia/Heparin-Induced Thrombocytopenia and Thrombosis Syndrome
Initial Novastan infusion doses are lower for seriously ill pediatric patients compared to adults with normal hepatic function [see Use in Specific Populations ].
In general, therapy with Novastan is monitored using the aPTT. Tests of anticoagulant effects (including the aPTT) typically attain steady-state levels within one to three hours following initiation of Novastan in patients without hepatic impairment [see Warnings and Precautions (5.2)]. Dose adjustment may be required to attain the target aPTT. Check the aPTT two hours after initiation of therapy and after any dose change to confirm that the patient has attained the desired therapeutic range.
2.5 Conversion to Oral Anticoagulant Therapy
Initiating Oral Anticoagulant Therapy
When converting patients from Novastan to oral anticoagulant therapy, consider the potential for combined effects on International Normalized Ratio (INR). To avoid prothrombotic effects and to ensure continuous anticoagulation when initiating warfarin, overlap Novastan Injection and warfarin therapy. There are insufficient data available to recommend the duration of the overlap. Initiate therapy using the expected daily dose of warfarin. A loading dose of warfarin should not be used.
The relationship between INR and bleeding risk is altered when Novastan and warfarin are coadministered. The combination of Novastan and warfarin does not cause further reduction in the vitamin K–dependent factor Xa activity than that which is seen with warfarin alone. The relationship between INR obtained on combined therapy and INR obtained on warfarin alone is dependent on both the dose of Novastan and the thromboplastin reagent used. The INR value on warfarin alone (INRW) can be calculated from the INR value on combination Novastan and warfarin therapy [see Drug Interactions (7.2) and Clinical Pharmacology (12.2)].
Coadministration of Warfarin and Novastan Injection at Doses Up to 2 mcg/kg/min
Measure INR daily while Novastan Injection and warfarin are coadministered. In general, with doses of Novastan Injection up to 2 mcg/kg/min, Novastan Injection can be discontinued when the INR is greater than 4 on combined therapy. After Novastan Injection is discontinued, repeat the INR measurement in 4 to 6 hours. If the repeat INR is below the desired therapeutic range, resume the infusion of Novastan Injection and repeat the procedure daily until the desired therapeutic range on warfarin alone is reached.
Coadministration of Warfarin and Novastan Injection at Doses Greater than 2 mcg/kg/min
For doses greater than 2 mcg/kg/min, the relationship of INR between warfarin alone to the INR on warfarin plus Novastan is less predictable. In this case, in order to predict the INR on warfarin alone, temporarily reduce the dose of Novastan Injection to a dose of 2 mcg/kg/min. Repeat the INR on Novastan Injection and warfarin 4 to 6 hours after reduction of the Novastan Injection dose and follow the process outlined above for administering Novastan Injection at doses up to 2 mcg/kg/min.

5 WARNINGS AND PRECAUTIONS
5.1 Risk of Hemorrhage
Hemorrhage can occur at any site in the body in patients receiving Novastan. An unexplained fall in hematocrit or hemoglobin or a fall in blood pressure should lead to consideration of a hemorrhagic event. Novastan Injection should be used with extreme caution in disease states and other circumstances in which there is an increased danger of hemorrhage. These include severe hypertension; immediately following lumbar puncture; spinal anesthesia; major surgery, especially involving the brain, spinal cord, or eye; hematologic conditions associated with increased bleeding tendencies such as congenital or acquired bleeding disorders and gastrointestinal lesions such as ulcerations.
Concomitant use of Novastan with antiplatelet agents, thrombolytics, and other anticoagulants may increase the risk of bleeding.
5.2 Use in Hepatic Impairment
Use caution when administering Novastan to patients with hepatic impairment by starting with a lower dose and carefully titrating until the desired level of anticoagulation is achieved. Upon cessation of Novastan infusion in the hepatically impaired patient, full reversal of anticoagulant effects may require longer than 4 hours due to decreased clearance and increased elimination half-life of Novastan . Use of Novastan in PCI patients with clinically significant hepatic disease or AST/ALT levels ≥ 3 times the upper limit of normal should be avoided.
5.3 Laboratory Tests
Anticoagulation effects associated with Novastan infusion at doses up to 40 mcg/kg/min correlate with increases of the activated partial thromboplastin time (aPTT). Although other global clot-based tests including prothrombin time (PT), the International Normalized Ratio (INR), and thrombin time (TT) are affected by Novastan, the therapeutic ranges for these tests have not been identified for Novastan therapy. In clinical trials in PCI, the activated clotting time (ACT) was used for monitoring Novastan anticoagulant activity during the procedure. The concomitant use of Novastan and warfarin results in prolongation of the PT and INR beyond that produced by warfarin alone .
6 ADVERSE REACTIONS
Because clinical trials are conducted under widely varying conditions, adverse event rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
To report SUSPECTED ADVERSE REACTIONS, contact TEVA USA, PHARMACOVIGILANCE at 1-866-832-8537 or drug.safetyNovastantevapharm.com; or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
6.1 Adverse Events in Patients with HIT (With or Without Thrombosis)
The following safety information is based on all 568 patients treated with Novastan in Study 1 and Study 2. The safety profile of the patients from these studies is compared with that of 193 historical controls in which the adverse events were collected retrospectively. Adverse events are separated into hemorrhagic and non-hemorrhagic events.
Major bleeding was defined as bleeding that was overt and associated with a hemoglobin decrease ≥ 2 g/dL, that led to a transfusion of ≥ 2 units, or that was intracranial, retroperitoneal, or into a major prosthetic joint. Minor bleeding was overt bleeding that did not meet the criteria for major bleeding.
Table 4 gives an overview of the most frequently observed hemorrhagic events, presented separately by major and minor bleeding, sorted by decreasing occurrence among argatroban-treated patients with HIT (with or without thrombosis).
Table 5 gives an overview of the most frequently observed non-hemorrhagic events sorted by decreasing frequency of occurrence (≥ 2%) among argatroban-treated HIT/HITTS patients.
6.2 Adverse Events in Patients with or at Risk for HIT Patients Undergoing PCI
The following safety information is based on 91 patients initially treated with Novastan and 21 patients subsequently re-exposed to Novastan for a total of 112 PCIs with Novastan anticoagulation. Adverse events are separated into hemorrhagic and non-hemorrhagic (Table 7) events.
Major bleeding was defined as bleeding that was overt and associated with a hemoglobin decrease ≥ 5 g/dL, that led to a transfusion of ≥ 2 units, or that was intracranial, retroperitoneal, or into a major prosthetic joint. The rate of major bleeding events in patients treated with Novastan in the PCI trials was 1.8%.
Table 7 gives an overview of the most frequently observed non-hemorrhagic events (> 2%), sorted by decreasing frequency of occurrence among argatroban-treated PCI patients.
There were 22 serious adverse events in 17 PCI patients (19.6% in 112 interventions). Table 8 lists the serious adverse events occurring in argatroban-treated patients with or at risk for HIT undergoing PCI.
6.3 Intracranial Bleeding in Other Populations
Increased risks for intracranial bleeding have been observed in investigational studies of Novastan for other uses. In a study of patients with acute myocardial infarction receiving both Novastan and thrombolytic therapy (streptokinase or tissue plasminogen activator), the overall frequency of intracranial bleeding was 1% (8 out of 810 patients). Intracranial bleeding was not observed in 317 subjects or patients who did not receive concomitant thrombolysis .
The safety and effectiveness of Novastan for cardiac indications other than PCI in patients with HIT have not been established. Intracranial bleeding was also observed in a prospective, placebo-controlled study of Novastan in patients who had onset of acute stroke within 12 hours of study entry. Symptomatic intracranial hemorrhage was reported in 5 of 117 patients (4.3%) who received Novastan at 1 to 3 mcg/kg/min and in none of the 54 patients who received placebo. Asymptomatic intracranial hemorrhage occurred in 5 (4.3%) and 2 (3.7%) of the patients, respectively.
6.4 Allergic Reactions
One hundred fifty-six allergic reactions or suspected allergic reactions were observed in 1,127 individuals who were treated with Novastan in clinical pharmacology studies or for various clinical indications. About 95% (148/156) of these reactions occurred in patients who concomitantly received thrombolytic therapy (e.g., streptokinase) or contrast media.
Allergic reactions or suspected allergic reactions in populations other than patients with HIT (with or without thrombosis) include (in descending order of frequency):
Limited data are available on the potential formation of drug-related antibodies. Plasma from 12 healthy volunteers treated with Novastan over 6 days showed no evidence of neutralizing antibodies. No loss of anticoagulant activity was noted with repeated administration of Novastan to more than 40 patients.
7 DRUG INTERACTIONS
If Novastan is to be initiated after cessation of heparin therapy, allow sufficient time for heparin’s effect on the aPTT to decrease prior to initiation of Novastan therapy.
7.2 Oral Anticoagulant Agents
Pharmacokinetic drug-drug interactions between Novastan and warfarin have not been demonstrated. However, the concomitant use of Novastan and warfarin (5 to 7.5 mg initial oral dose, followed by 2.5 to 6 mg/day orally for 6 to 10 days) results in prolongation of the prothrombin time (PT) and International Normalized Ratio (INR) [see Dosage and Administration (2.5) and Clinical Pharmacology (12.2)].
No drug-drug interactions have been demonstrated between Novastan and concomitantly administered aspirin or acetaminophen [see Clinical Pharmacology (12.3)].
7.4 Thrombolytic Agents
The safety and effectiveness of Novastan with thrombolytic agents have not been established .
7.5 Glycoprotein IIb/IIIa Antagonists
The safety and effectiveness of Novastan with glycoprotein IIb/IIIa antagonists have not been established.
8 USE IN SPECIFIC POPULATIONS
Pregnancy Category B
There are no adequate and well-controlled studies of Novastan use in pregnant women. Developmental studies performed in rats with Novastan at intravenous doses up to 27 mg/kg/day (0.3 times the maximum recommended human dose, based on body surface area) and in rabbits at intravenous doses up to 10.8 mg/kg/day (0.2 times the maximum recommended human dose, based on body surface area) have revealed no evidence of impaired fertility or harm to the fetus. Because animal reproductive studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
8.3 Nursing Mothers
It is not known whether Novastan is excreted in human milk. Novastan is detected in rat milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Novastan, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
8.4 Pediatric Use
The safety and effectiveness of Novastan, including the appropriate anticoagulation goals and duration of therapy, have not been established among pediatric patients. Novastan was studied among 18 seriously ill pediatric patients who required an alternative to heparin anticoagulation. Most patients were diagnosed with HIT or suspected HIT. Age ranges of patients were < 6 months, n = 8; six months to < 8 years, n = 6; 8 to 16 years, n = 4. All patients had serious underlying conditions and were receiving multiple concomitant medications. Thirteen patients received Novastan solely as a continuous infusion. Dosing was initiated in the majority of these 13 patients at 1 mcg/kg/min. Dosing was titrated as needed to achieve and maintain an aPTT of 1.5 to 3 times the baseline value. Most patients required multiple dose adjustments to maintain anticoagulation parameters within the desired range. During the 30-day study period, thrombotic events occurred during Novastan administration to two patients and following Novastan discontinuation in three other patients. Major bleeding occurred among two patients; one patient experienced an intracranial hemorrhage after 4 days of Novastan therapy in the setting of sepsis and thrombocytopenia. Another patient completed 14 days of Novastan treatment in the study, but experienced an intracranial hemorrhage while receiving Novastan following completion of the study treatment period.
When Novastan is used among seriously ill pediatric patients with HIT/HITTS who require an alternative to heparin and who have normal hepatic function, initiate a continuous infusion of Novastan at a dose of 0.75 mcg/kg/min. Initiate the infusion at a dose of 0.2 mcg/kg/min among seriously ill pediatric patients with impaired hepatic function . Check the aPTT two hours after the initiation of the Novastan infusion and adjust the dose to achieve the target aPTT. These dose recommendations are based upon a goal of aPTT prolongation of 1.5 to 3 times the baseline value and avoidance of an aPTT > 100 seconds. Increments of 0.1 to 0.25 mcg/kg/min for pediatric patients with normal hepatic function and increments of 0.05 mcg/kg/min or lower for pediatric patients with impaired hepatic function may be considered but dose selection must take into account multiple factors including the current Novastan dose, the current aPTT, target aPTT, and the clinical status of the patient. These dose recommendations are based upon a goal of aPTT prolongation of 1.5 to 3 times the baseline value and avoidance of an aPTT > 100 seconds.
8.5 Geriatric Use
Of the total number of subjects (1340) in clinical studies of Novastan, 35% were 65 and over. In the clinical studies of adult patients with HIT (with or without thrombosis), the effectiveness of Novastan was not affected by age. No trends were observed across age groups for both aPTT and the ACT. The safety analysis did suggest that older patients tended to have an increased incidence of events compared to younger patients; however, older patients had increased underlying conditions, which may predispose them to events. The studies were not sized appropriately to detect differences in safety between age groups.
8.6 Hepatic Impairment
Dose reduction and careful titration are required when administering Novastan to patients with hepatic impairment. Reversal of anticoagulation effect may be prolonged in this population .
Excessive anticoagulation, with or without bleeding, may be controlled by discontinuing Novastan or by decreasing the Novastan dose. In clinical studies, anticoagulation parameters generally returned from therapeutic levels to baseline within 2 to 4 hours after discontinuation of the drug. Reversal of anticoagulant effect may take longer in patients with hepatic impairment.
No specific antidote to Novastan is available; if life-threatening bleeding occurs and excessive plasma levels of Novastan are suspected, discontinue Novastan immediately and measure aPTT and other coagulation parameters. When Novastan was administered as a continuous infusion (2 mcg/kg/min) prior to and during a 4-hour hemodialysis session, approximately 20% of Novastan was cleared through dialysis.
Single intravenous doses of Novastan at 200, 124, 150, and 200 mg/kg were lethal to mice, rats, rabbits, and dogs, respectively. The symptoms of acute toxicity were loss of righting reflex, tremors, clonic convulsions, paralysis of hind limbs, and coma.
Novastan is a synthetic direct thrombin inhibitor and the chemical name is 1-[5-[amino]1-oxo-2-[[(1,2,3,4-tetrahydro-3-methyl-8-quinolinyl)sulfonyl]amino]pentyl]-4-methyl-2-piperidinecarboxylic acid, monohydrate. Novastan has 4 asymmetric carbons. One of the asymmetric carbons has an R configuration (stereoisomer Type I) and an S configuration (stereoisomer Type II). Novastan consists of a mixture of R and S stereoisomers at a ratio of approximately 65:35.
The molecular formula of Novastan is C23H36N6O5S∙H2O. Its molecular weight is 526.66 g/mol. The structural formula is:
Figure 4. Time to First Event for the Composite Efficacy Endpoint: HITTS Patients STUDY 1
In Study 2, a total of 264 patients were enrolled as follows: HIT (n = 125) or HITTS (n = 139). There was a significant improvement in the composite efficacy outcome for argatroban-treated patients, versus the same historical control group from Study 1, among patients having HIT (25.6% vs. 38.8%), patients having HITTS (41.0% vs. 56.5%), and patients having either HIT or HITTS (33.7% vs. 43.0%). Time-to-event analyses showed significant improvements in the time-to-first event in patients with HIT or HITTS treated with Novastan versus those in the historical control group. The between-group differences in the proportion of patients who remained free of death, amputation, or new thrombosis were statistically significant in favor of Novastan.
In Study 1, the mean (± SE) dose of Novastan administered was 2.0 ± 0.1 mcg/kg/min in the HIT arm and 1.9 ± 0.1 mcg/kg/min in the HITTS arm. Seventy-six percent of patients with HIT and 81% of patients with HITTS achieved a target aPTT at least 1.5-fold greater than the baseline aPTT at the first assessment occurring on average at 4.6 hours (HIT) and 3.9 hours (HITTS) following initiation of Novastan therapy. No enhancement of aPTT response was observed in subjects receiving repeated administration of Novastan.
Platelet Count Recovery
In Study 1, 53% of patients with HIT and 58% of patients with HITTS, had a recovery of platelet count by Day 3. Platelet Count Recovery was defined as an increase in platelet count to > 100,000/µL or to at least 1.5-fold greater than the baseline count (platelet count at study initiation) by Day 3 of the study.
Figure 3. Figure 4.
14.2 Percutaneous Coronary Intervention (PCI) Patients with or at Risk for HIT
In 3 similarly designed trials, Novastan was administered to 91 patients with current or previous clinical diagnosis of HIT or heparin-dependent antibodies, who underwent a total of 112 percutaneous coronary interventions (PCIs) including percutaneous transluminal coronary angioplasty (PTCA), coronary stent placement, or atherectomy. Among the 91 patients undergoing their first PCI with Novastan, notable ongoing or recent medical history included myocardial infarction (n = 35), unstable angina (n = 23), and chronic angina (n = 34). There were 33 females and 58 males. The average age was 67.6 years (median 70.7, range 44 to 86), and the average weight was 82.5 kg (median 81.0 kg, range 49 to 141).
Twenty-one of the 91 patients had a repeat PCI using Novastan an average of 150 days after their initial PCI. Seven of 91 patients received glycoprotein IIb/IIIa inhibitors. Safety and efficacy were assessed against historical control populations who had been anticoagulated with heparin.
All patients received oral aspirin (325 mg) 2 to 24 hours prior to the interventional procedure. After venous or arterial sheaths were in place, anticoagulation was initiated with a bolus of Novastan of 350 mcg/kg via a large-bore intravenous line or through the venous sheath over 3 to 5 minutes. Simultaneously, a maintenance infusion of 25 mcg/kg/min was initiated to achieve a therapeutic activated clotting time (ACT) of 300 to 450 seconds. If necessary to achieve this therapeutic range, the maintenance infusion dose was titrated (15 to 40 mcg/kg/min) and/or an additional bolus dose of 150 mcg/kg could be given. Each patient’s ACT was checked 5 to 10 minutes following the bolus dose. The ACT was checked as clinically indicated. Arterial and venous sheaths were removed no sooner than 2 hours after discontinuation of Novastan and when the ACT was less than 160 seconds.
If a patient required anticoagulation after the procedure, Novastan could be continued, but at a lower infusion dose between 2.5 and 5 mcg/kg/min. An aPTT was drawn 2 hours after this dose reduction and the dose of Novastan then was adjusted as clinically indicated (not to exceed 10 mcg/kg/min), to reach an aPTT between 1.5 and 3 times baseline value (not to exceed 100 seconds).
In 92 of the 112 interventions (82%), the patient received the initial bolus of 350 mcg/kg and an initial infusion dose of 25 mcg/kg/min. The majority of patients did not require additional bolus dosing during the PCI procedure. The mean value for the initial ACT measurement after the start of dosing for all interventions was 379 sec (median 338 sec; 5th percentile-95th percentile 238 to 675 sec). The mean ACT value per intervention over all measurements taken during the procedure was 416 sec (median 390 sec; 5th percentile-95th percentile 261 to 698 sec). About 65% of patients had ACTs within the recommended range of 300 to 450 seconds throughout the procedure. The investigators did not achieve anticoagulation within the recommended range in about 23% of patients. However, in this small sample, patients with ACTs below 300 seconds did not have more coronary thrombotic events, and patients with ACTs over 450 seconds did not have higher bleeding rates.
Acute procedural success was defined as lack of death, emergent coronary artery bypass graft (CABG), or Q-wave myocardial infarction. Acute procedural success was reported in 98.2% of patients who underwent PCIs with Novastan anticoagulation compared with 94.3% of historical control patients anticoagulated with heparin (p = NS). Among the 112 interventions, 2 patients had emergency CABGs, 3 had repeat PTCAs, 4 had non-Q-wave myocardial infarctions, 3 had myocardial ischemia, 1 had an abrupt closure, and 1 had an impending closure (some patients may have experienced more than 1 event). No patients died.
