(1) Background: Cardiovascular diseases, in particular, myocardial infarction (MI), are the main threats to human health in modern times. Cardiac rehabilitation (CR), and especially increased physical activity, significantly prevent the consequences of MI. The aim of this study was to assess physical performance in patients after MI before and after CR. (2) Methods: 126 patients after MI were examined. They were admitted to the cardiac rehabilitation ward twice: in the 3rd month after MI, and then in the 6th month after the last rehabilitation session. CR lasted 20 treatment days (4 weeks with 5 treatment days and 2 days’ break). The exercise stress test on the treadmill and a 6-minute walk test (6MWT) were used to assess physical performance. Patients were assigned to an appropriate rehabilitation model due to their health condition. (3) Results: In the studied group, the exercise stress test time and the metabolic equivalent of task (MET), the maximal oxygen consumption (VO2max), and 6MWT score increased significantly (p = 0.0001) at two time-points of observation. (4) Conclusion: CR significantly improves physical performance in patients after MI.

Abstract Background Exercise-based cardiac rehabilitation for coronary artery disease (CAD) is associated with lower cardiovascular mortality. On the other hand, acute strenuous exercise has been linked to cardiovascular complications such as acute myocardial infarction (AMI) and sudden cardiac death. One of the pathophysiological mechanisms involved in these outcomes might be an increase in platelet aggregability after exercise. Although previous studies showed higher platelet aggregability after exercise among stable CAD patients on aspirin treatment, there is no data regarding the effect of exercise on platelet activity in post-AMI patients on dual anti-platelet therapy (DAPT). Purpose To evaluate the effect of high-intensity exercise on platelet aggregability in sedentary post-AMI patients on DAPT. Methods Platelet function was analyzed immediately before and after maximal cardiopulmonary exercise test (CPET) on cycle ergometer utilizing a personalized ramp protocol and aiming to achieving peak exercise in around 10 min. The CPET was done within 31±4 days after uncomplicated AMI. Platelet aggregability was assessed by Multiplate®ADPtest (MP-ADP) and Multiplate® ASPItest (MP-ASPI) measured as area under the curve (AUC). Reticulated platelets were measured concomitantly to MP-ADP e MP-ASPI using a fully automated flow cytometer (Sysmex XN-2000®) to determine absolute immature platelet count (IPC) per 103/microliter. Continuous variables were expressed as means ±standard deviation or as median and 25th–75th percentiles if not Gaussian distributed. Comparisons between the pre- and post-CPET assessments were performed using Wilcoxon signed rank test. Results We analyzed 81 sedentary patients (mean age 58.3±10.1 years-old, 76.5% men) after AMI (50.6% with ST-elevation myocardial infarction, mean left ventricular ejection fraction after index event 55±11.7%, 98.8% on statin and 85.5% on beta-blocker treatment). Platelet aggregability, either by MP-ADP or MP-ASPI, and IPC were significantly increased after CPET (table). Platelet function after CPET Before CPET After CPET p-value Multiplate® ADPtest (AUC) – median (25th–75th percentiles) 32.0 (22.0–48.5) 37.0 (26.0–55.2) 0.003 Multiplate® ASPItest (AUC) – median (25th–75th percentiles) 17.0 (12.7–22.0) 22.0 (16.7–28.0) <0.001 Immature platelet count (103/microliter) – median (25th–75th percentiles) 9.5 (6.8–13.8) 9.6 (6.6–16.5) 0.006 CPET: cardiopulmonary exercise test; AUC: area under the curve. Conclusion On this post-AMI population, platelet was hyperactivated after exercise stress test despite the use of DAPT. These findings suggest that, even when properly treated, post-AMI patients might be at higher risk of ischemic complications after high-intensity exercises, reinforcing the importance of tailoring exercise prescription in this population.

AbstractFifty patients with myocardial infarction were recruited from a hospital based Cardiac Education and Assessment Program (CEAP) in Sydney, Australia. The Exercise Motivation Inventory-2 (EMI-2) and the Depression, Anxiety and Stress Scale (DASS) were administered prior to commencement in the program and re-administered by telephone interview at 5-month followup. Four exercise adherence measures were completed: attendance, exercise stress test, self-report ratings and a 7-day activity recall interview. There was a 46% adherence rate for MI patients during the hospital based CEAP. Of those individuals who completed CEAP, 91% obtained functional improvement on the exercise stress test. For the 38 patients who were followed-up by telephone interview at 5 months, 71% were exercising according to CEAP prescription. Higher levels of anxiety were associated with lower levels of self-reported exercise adherence. The 3 strongest motivations for exercise in this group of MI patients were all health related; wanting to be free from illness, maintaining good health and recovering from the effects of coronary heart disease. The discussion highlights the implications of these findings for cardiac rehabilitation programs and the need for empirically driven guidelines for measuring exercise adherence.

Background: Exercise stress test (EST) is recommended as the first-line investigation in major guidelines. It believed as a safe procedure. However, there is unignorable complications include hospitalisation, acute myocardial infarction and sudden cardiac death. Case Presentation: We describe a case of a 56-year-old male who underwent exercise stress test and complicated with hemodynamically unstable ventricular tachycardia. He was resuscitated and diagnosed with acute anterior ST-elevation myocardial infarction. Subsequent coronary angiogram showed severe two vessels disease. Conclusion: This illustrates the importance to identify a cohort of high-risk patient pre-EST, along with proper supervision and well-staffed exercise stress test lab in order to provide appropriate lifesaving treatment.

Introduction: Concerning the poor clinical outcomes in cases of acute myocardial infarction (AMI) with bifurcation lesions undergoing primary percutaneous coronary intervention (PCI), we described a successful application of modified flower petal technique and called it the REVERSE modified flower petal technique in a patient with AMI. Case Presentation: A 56-years-old man who suffered from chest pain was admitted to the emergency ward. After clinical examination, the primary diagnosis was acute anterolateral MI. Therefore, PCI on left anterior dimension (LAD) and diagonal arteries using modified flower petal stenting was performed in the side branch, which we called it REVERSE modified flower petal. Conclusions: Modified flower petal stenting was performed by the REVERSE mechanism as described in the report of the new intervention (2.5 × 18). The follow-up after 24 months by the exercise stress test using the Bruce protocol supported the success of the intervention.
