Objectives. This study investigated the relationship between the timing of ventricular tachycardia or ventricular fibrillation (VT or VF) and prognosis in patients undergoing primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). Background. It is unknown whether the timing of VT/VF occurrence affects the prognosis of patients with AMI. Methods. From January 2004 to December 2014, 1004 patients with AMI underwent primary PCI. Of these patients, 888 did not have VT/VF (non-VT/VF group) and 116 had sustained VT/VF during prehospitalization or hospitalization. Patients with VT/VF were divided into two groups: early VT/VF (VT/VF occurrence before and within 2 days of admission, 92 patients) and late VT/VF (VT/VF occurrence >2 days after admission; 24 patients) groups. Results. The frequency of VT/VF occurrence was high between the day of admission and the 2nd day and between days 6 and 10 of hospitalization. The late VT/VF group had a significantly longer onset-to-balloon time, lower ejection fraction, poorer renal function, and higher creatine phosphokinase (CK)-MB level on admission (p< 0.001). They also had a lower 30-day cardiac survival rate than the early VT/VF and non-VT/VF groups (42% vs. 76% vs. 96%, p < 0.001). Moreover, independent predictors of in-hospital cardiac mortality among patients with AMI who had sustained VT/VF were higher peak CK-MB [Odds ratio (OR: 1.001, 95%confidence interval (CI): 1.000-1.002, p= 0.03)], higher Killip class (OR: 1.484, 95%CI 1.017-2.165, p= 0.04), and late VT/VF (OR: 3.436, 95%CI 1.115-10.59, p= 0.03). Conclusions. The timing of VT/VF occurrences had a bimodal peak. Although late VT/VF occurrence after primary PCI was less frequent than early VT/VF occurrence, patients with late VT/VF had a very poor prognosis.

Thrombolytic therapy kick-started the era of modern cardiology but in the last few decades it has been largely supplanted by primary percutaneous coronary intervention (PCI) as the go-to treatment for acute myocardial infarction. However, these agents remain important for vast populations without access to primary PCI and acute ischemic stroke. More innovative uses have recently come up for the treatment of a variety of conditions. This article summarizes the history, evidence base and current use of thrombolytics in cardiovascular disease.

OBJECTIVES To determine clinical outcome and to nd out the association between participation of patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) in cardiac rehabilitation programme. DESIGN A Prospective observational study. STUDY AREA : Department of Cardiology, Institute of Postgraduate Medical Education and Research,Kolkata. PARTICIPANTS: Patients aged ≥18 years who underwent PCI due to AMI. OUTCOME MEASURES The outcomes were subsequent myocardial infarction, revascularisation, all-cause readmission, cardiac readmission, all-cause mortality and cardiac mortality. RESULT: The data of 1107 patients were included and 60.07%% of them participated in CR program. The risks of revascularisation, all cause readmission and cardiac readmission among CR participants were compared. The results of those analysis were consistent and showed that the CR participants had lower allcause mortality ,cardiac mortality,all cause readmission, cardiac admission. However no effect was observed for subsequent myocardial infarction or revascularisation. CONCLUSIONS: It was suggested CR participation may reduce the risk of all-cause mortality ,cardiac mortality, all cause readmission and cardiac admission.

Background: Assessment of cardiac biomarker release has been traditionally used to estimate the size of myocardial damage after acute myocardial infarction (AMI). However, the significance of cardiac biomarkers in the setting of primary percutaneous coronary intervention (PCI) has not been systematically studied in a large patient cohort. We evaluated the usefulness of serial and single time-point measures of various cardiac biomarkers (creatine kinase (CK), CK-MB, troponin T and I) in predicting infarct size and left ventricular ejection fraction (LVEF) after primary PCI. Methods: EVOLVE (Evaluation of MCC-135 for Left Ventricular Salvage in AMI) was a randomized double-blind, placebo-controlled trial comparing the efficacy of intracellular calcium modulator as an adjunct to primary PCI in patients with first large AMI. Levels of cardiac biomarkers (CK, CK-MB mass, troponin T and I) were determined in 375 patients at baseline before PCI and 2, 4, 12, 24, 48 and 72 hours thereafter. Single photon emission computed tomography imaging was performed to measure infarct size and LVEF on day 5. Results: Area under curve and peak concentrations of all cardiac markers: CK, CK-MB mass, troponin T and troponin I were significantly correlated with myocardial infarct size and LVEF determined on day 5 (Spearman correlation, all P< 0.001; Table ). Troponin I, however provided the best predictor and a single measure at 72 hr was a strong indicator of both infarct size and LVEF. Using receiver operator characteristics curve, troponin I cutoff value of >55 pg/mL at 72 hr has 90% sensitivity and 70% specificity for detection of large infarct size≥10% ( c =0.88; P< 0.001). Conclusions: Plasma levels of CK, CK-MB, troponin T and troponin I remain useful predictors of infarct size and cardiac function in the era of primary PCI for AMI. A single measurement of circulating troponin I at 72 hours can provide an effective and convenient indicator of infarct size and LVEF in clinical practice. Correlation of cardiac biomarkers with Day 5 SPECT determined infarct size and LVEF

Abstract Background The proportion of the octogenarian population is expanding especially in Eastern society. Due to the clustering of risk factors, acute myocardial infarction (AMI) represents a major cardiovascular complication in octogenarian subjects. This suggests the need to further optimize their therapeutic management to prevent future cardiac events after AMI. However, analysis of clinical characteristics and cardiovascular outcomes in octogenarian subjects with AMI who received the current established medical therapies is limited. Purpose To investigate clinical features and prognosis in octogenarian AMI subjects treated with percutaneous coronary intervention (PCI). Methods We analyzed 1547 AMI subjects underwent PCI between 2007 and 2017. Baseline characteristics and the occurrence of composite major adverse cardiovascular events (cardiac death, non-fatal MI, revascularization, heart failure and stroke) were compared in octogenarian and non-octogenarian subjects. Results 22.0% (340/1547) of study subjects was octogenarian. They were more likely to have chronic kidney disease (CKD) and a lower level of LDL-C on admission (Table). Moreover, a higher prevalence of severer Killip class and LVEF <30% were observed in octogenarians (Table). However, they were not optimally treated with the established medical therapies at discharge (Table). During the observational period (median=3.1 years), the composite of cardiovascular events more frequently occurred in octogenarian subjects. Of note, they exhibited a 2.15-fold and 3.01-fold increased risk for heart failure and stroke events, respectively (Figure). Table 1 Non-Octogenarian (n=1207) Octogenarian (n=340) P-value CKD* (%) 33.8 63.2 <0.0001 LVEF <30% (%) 5.7 10.3 0.02 Killip class 1.33±0.03 1.55±0.05 <0.0001 LDL-C (mmol/L) 3.20±0.03 2.80±0.05 <0.0001 Statin (%) 86.3 78.2 0.0006 Beta-blocker (%) 74.0 65.8 0.005 ACE-I/ARB (%) 87.3 76.6 <0.0001 DAPT (%) 86.0 88.6 0.42 *CKD is defined as estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2. Figure 1 Conclusions Octogenarian subjects with AMI were high-risk group associated with heart failure and stroke events. Their distinct clinical backgrounds may affect the adoption of optimal medical therapies, potentially resulting in worse cardiovascular outcomes. Further intensified management should be applied to octogenarian subjects with AMI.

Background: Cardiovascular disease is the most common cause of death around the world. QT dispersion is one of the parameters that used for evaluation of ventricular arrhythmia. Primary PCI increases probability of coronary artery and reperfusion of the ventricular arrhythmia. The aim of this study was to determine effect of primary percutaneous coronary intervention (PCI) on ventricular repolarization through evaluation of QT dispersion in patient with acute myocardial infarction. Methods: In this pre-post test study, 77 patients with acute ST with elevated myocardial infarction under primary PCI were investigated. The ECG and ST dispersion before PCI and 24 hours after PCI were determined and then the amount of QTd was calculated. The repeated measurement ANOVA was used to compare QTd of pre- PCI treatment and QTd in 24 hours after PCI. Data analysis was performed using statistical software SPSS ver.17. Results: From 77 participants, 60 were male and 17 were female. 43 (55.8%) had a MI position in ANT, PRE, and EXT, 33 (42.9%) had in the INF, and only one person (1.3%) had a MI position in LAT. The results showed that mean QT dispersion in ECG, 24h after primary PCI, for most of measured variables was deceased compare to before primary PCI, but the difference was not significant. Conclusions: The amount of QTd 24 hours after PCI decreased but its decline was not significant. With regards to lack of convenience data, more researches are recommended in this field.
