Impact of platelet phenotype on myocardial infarction
In acute myocardial infarction patients the injured vascular wall triggers thrombus formation in the damage site. Fibrin fibers and blood cellular elements are the major components of thrombus formed in acute occlusion of coronary arteries. It has been established that the initial thrombus is primarily composed of activated platelets rapidly stabilized by fibrin fibers. This review highlights the role of platelet membrane phenotype in pathophysiology of myocardial infarction. Here, we regard platelet phenotype as quantitative and qualitative parameters of the plasma membrane outer surface, which are crucial for platelet participation in blood coagulation, development of local inflammation and tissue repair
High-dose streptokinase in the treatment of acute massive pulmonary embolism complicated with cardiogenic shock, respiratory arrest and ventricular fibrillation
Background. Despite advances in prophylaxis, diagnostic modalities, and therapeutic options, pulmonary embolism remains a commonly undiagnosed entity with lethal outcome. Clinically, pulmonary embolism ranges from massive thromboembolism with cardiogenic shock to asymptomatic, microebolism with anatomically small emboli without hemodynamic, respiratory or other disturbances. Case report. A patient with massive pulmonary embolism complicated with ventricular fibrillation, respiratory arrest and cardiogenic shock was treated with a total dose of 3 750 000 IU of intravenous streptokinase in the 8- hour time period. After successful cardiopulmonary resuscitation, and thrombolytic therapy, the patient regained hemodynamic stability six hours after admission; all clinical and electrocardiographic signs of the right ventricle insufficiency disappeared. Conclusion. This case report suggested that treatment with the high-dose of streptokinase could be beneficial in the patients with massive pulmonary embolism complicated with cardiogenic shock, which must be confirmed by further randomized trials.</jats:p
Impact of the Combined Left Ventricular Systolic and Renal Dysfunction on One-Year Outcomes after Primary Percutaneous Coronary Intervention

Predictors of Major Adverse Cardiovascular Events in Stable Patients After ST Elevation Myocardial Infarction
Background/aim: The aim of this study was to determine predictors of major adverse cardiovascular events, including MACE (mortality, non-fatal recurrent infarction, non-fatal stroke, and target vessel revascularization-TVR) in stable post-STEMI patients. Method: We analyzed STEMI patients without cardiogenic shock at admission included in our STEMI Register. The patients were treated with primary PCI. The follow-up period was eight years. Results: From 1 December 2006 to 31 December 2016, a total of 3079 patients were included in the Register. In the first year, MACE was registered in 348 (11.3%) patients. The remaining patients were considered stable. They were included in further analysis. At eight years, the rates were as follows: MACE 3.9%, non-fatal recurrent infarction 2.1%, TVR 1.8%, non-fatal stroke 0.5%, and mortality 2.1%. Predictors for 8-year MACE were age >60 years (60–69 vs. <60 years HR 1.65; 70–79 vs. <60 years HR 1.82; ≥80 vs. <60 years HR 3.16), EF < 50% (EF 40–49% HR 2.38; EF < 40% HR 2.32), diabetes mellitus (HR 1.49), and 3-vessel coronary artery disease (HR 1.44). Conclusions: Four predictors identified stable post-STEMI patients who remained at a higher risk for the occurrence of MACE. Stable post-STEMI patients with one or more of these risk factors may require more aggressive secondary prevention measures or a personalized approach to improve their prognosis
Long-Term Prognostic Impact of Stress Hyperglycemia in Non-Diabetic Patients Treated with Successful Primary Percutaneous Coronary Intervention
Background: stress hyperglicemia (SH) is common in patients with ST-elevation myocardial infraction (STEMI). The aims of this study were to analyze the impact of SH on the incidence of all-cause mortality and major adverse cardiovascular events (MACE-cardiovascular death, nonfatal reinfarction, target vessel revascularization, and stroke) in STEMI patients without diabetes mellitus (DM) who have been treated successfully with primary PCI (pPCI). Method: we analyzed 2362 STEMI patients treated with successful pPCI (post-procedural flow TIMI = 3) and without DM and cardiogenic shock at admission. Stress hyperglycemia was defined as plasma glucose level above 7.8 mmol/L at admission. The follow-up period was 8 years. Results: incidence of SH was 26.9%. Eight-year all-cause mortality and MACE rates were significantly higher in patients with SH, as compared to patients without SH (9.7% vs. 4.2%, p < 0.001, and 15.7% vs. 9.4%, p < 0.001). SH was an independent predictor of short- and long-term all-cause mortality (HR 2.19, 95%CI 1.16–4.18, and HR 1.99, 95%CI 1.03–3.85) and MACE (HR 1.49, 95%CI 1.03–2.03, and HR 1.35, 95%CI 1.03–1.89). Conclusion: despite successful revascularization, SH at admission was an independent predictor of short-term and long-term (up to eight years) all-cause mortality and MACE, but its negative prognostic impact was stronger in short-term follow-up
Impact of Multivessel Coronary Artery Disease on Long Term Prognosis in Patients with ST-segment Elevation Myocardial Infarction
Prognostic Impact of Non-Cardiac Comorbidities on Long-Term Prognosis in Patients with Reduced and Preserved Ejection Fraction following Acute Myocardial Infarction
Background: We aimed to analyze the prevalence and long-term prognostic impact of non-cardiac comorbidities in patients with reduced and preserved left-ventricular ejection fraction (EF) following ST-elevation myocardial infarction (STEMI). Method: A total of 3033 STEMI patients undergoing primary percutaneous coronary intervention (pPCI) were divided in two groups: reduced EF < 50% and preserved EF ≥ 50%. The follow-up period was 8 years. Results: Preserved EF was present in 1726 (55.4%) patients and reduced EF was present in 1389 (44.5%) patients. Non-cardiac comorbidities were more frequent in patients with reduced EF compared with patients with preserved EF (38.9% vs. 27.4%, respectively, p < 0.001). Lethal outcome was registered in 240 (17.2%) patients with reduced EF and in 40 (2.3%) patients with preserved EF, p < 0.001. Diabetes and chronic kidney disease (CKD) were independent predictors for 8-year mortality in patients with preserved EF. In patients with reduced EF, CKD was independently associated with 8-year mortality. Conclusion: In patients who had reduced EF, the prevalence of non-cardiac comorbidities was higher than in patients who had preserved EF after STEMI. Only diabetes mellitus and CKD were independently associated with 8-year mortality in analyzed patients
Using the RISK-PCI Score in the Long-Term Prediction of Major Adverse Cardiovascular Events and Mortality after Primary Percutaneous Coronary Intervention
Background/Aim. The RISK-PCI is a simple score for the prediction of 30-day major adverse cardiovascular events (MACE) and mortality in patients treated with primary PCI (pPCI). The aim of the present study is to evaluate the prognostic performance of the RISK-PCI score in predicting MACE and mortality in the long-term follow-up of STEMI patients treated with pPCI. Method. The present study enrolled 2,096 STEMI patients treated with pPCI included in the RISK-PCI trial. Patients presenting with cardiogenic shock were excluded. The composite end-point MACE comprising cardiovascular mortality, nonfatal reinfarction and stroke. Patients were followed up at 6 years after enrollment. Results. One-year and 6-year MACE occurred in 229 (10.9%) and 285 (13.6%) patients, respectively; and 1-year and 6-year mortality occurred in 128 (6.2%) and 151 (7.2%) patients, respectively. The RISK-PCI score was an independent predictor for 1-year MACE (HR 1.24, 95% CI 1, 18–1.31, p<0.001), 6-year MACE (HR 1.22, 95% CI 1.16–1.28, p<0.001), 1-year mortality (HR 1.21, 95% CI 1.13–1.29, p<0.001), and 6-year mortality (HR 1.23, 95% CI 1.15–1.31, p<0.001). The discrimination of the RISK-PCI score to predict 1-year and 6-year MACE and mortality was good: for 1-year MACE c-statistic 0.78, for 6-year MACE c-statistic 0.75, for 1-year mortality c-statistic 0.87, and for 6-year mortality c-statistic 0.83. The nonsignificant Hosmer–Lemeshow goodness-of-fit estimates for 1-year MACE (p=0.619), 6-year MACE (p=0.319), 1-year mortality (p=0.258), and 6-year mortality (p=0.540) indicated a good calibration of the model. Conclusion. The RISK-PCI score demonstrates good characteristics in the assessment of the risk for the occurrence of MACE and mortality during long-term follow-up after pPCI
