Introduction: With advancement in interventional cardiology an increase in the number of percutaneous coronary intervention (PCI) procedures has been noted in the elderly. However, the post procedure complication and mortality remain a challenge for the physicians. This study aimed to estimate the survival among men and women above 80 years of age who undergo primary PCI for treatment of ST elevation myocardial infarction. Methods: We analyzed the data collected prospectively from our cardiac center. The patients were followed up over 10 years. Most patient received stents followed by anti-platelet drugs and preventive measures to avoid further cardiac event. Kaplan Meier curves were generated to study survival post PCI (SPSS v2.2). Survival curves were developed to determine the influence of age, sex, type of stent and degree of coronary flow (TIMI 0-3) on post procedure survival. Results: From 2010 to 2019, total 502 patients >80 years received PCI (282 males, 218 females). The median survival in the male and female population were 2.16 yrs. (95% CI 1.66 - 2.66) and 2.36 yrs. (95% CI 1.72-2.99)(P= 0.18). Significant difference of around 1 year (2.7 yrs. octogenarian vs 1.6 yrs. nonagenarian, p<0.001, see figure 1) was found in post PCI survival between octogenarian and nonagenarian. However, the survival was longer in case of Bare metal stents (BMS)(n= 113) as compared to Drug eluting stents(DES)(n= 274) (2.7 yrs. vs. 2.0yr, p<0.001). Similarly, post procedure TIMI flow analysis shows maximum survival in TIMI 3 followed by TIMI 2 and TIMI 1 ensuring the significance of TIMI grade flow. Conclusions: Our results demonstrate that PPCI in elderly patients have a better outcome and longer survival in octogenarians than nonagenarians. Similarly, use of BMS could be considered over DES in population above 80 years of age irrespective of gender. No difference in post PCI survival in male and female population.

Objective. The most important step in the treatment of ST elevation myocardial infarction is to sustain myocardial blood supply as soon as possible. The two main treatment methods used today to provide myocardial reperfusion are thrombolytic therapy and percutaneous coronary intervention. In our study, reperfusion arrhythmias were investigated as if they are indicators of coronary artery patency or ongoing ischemia after revascularization.Methods. 151 patients with a diagnosis of acute ST elevation myocardial infarction were investigated. 54 patients underwent primary percutaneous coronary intervention and 97 patients were treated with thrombolytic therapy. The frequency of reperfusion arrythmias following revascularization procedures in the first 48 hours after admission was examined. The relation between reperfusion arrhythmias, ST segment regression, coronary artery patency, and infarct related artery documented by angiography were analyzed.Results. There was no statistically significant difference between the two groups in the frequency of reperfusion arrhythmias (P=0.355). Although angiographic vessel patency was higher in patients undergoing percutaneous coronary intervention, there was no significant difference between the patency rates of each group with and without reperfusion arrythmias.Conclusion. Our study suggests that recorded arrhythmias following different revascularization procedures in acute ST elevation myocardial infarction may not always indicate vessel patency and reperfusion. Ongoing vascular occlusion and ischemia may lead to various arrhythmias which may not be distinguished from reperfusion arrhythmias.

This article reviews optimum therapies for the management of ST-elevation myocardial infarction (STEMI) with primary percutaneous coronary intervention (PCI). Optimum anti-thrombotic therapy includes aspirin, bivalirudin and the new anti-platelet agents prasugrel or ticagrelor. Stent thrombosis (ST) has been a major concern but can be reduced by achieving optimal stent deployment, use of prasugrel or ticagrelor, selective use of drug-eluting stents (DES) and use of new generation DES. Large thrombus burden is often associated poor outcomes. Patients with moderate to large thrombus should be managed with aspiration thrombectomy and patients with giant thrombus should be treated with glycoprotein IIb/IIIa inhibitors and may require rheolytic thrombectomy. The great majority of STEMI patients presenting at non-PCI hospitals can best be managed with transfer for primary PCI even with substantial delays. A small group of patients who present very early, who are at high clinical risk and have long delays to PCI, may best be treated with a pharmaco-invasive strategy.

BACKGROUND Coronary microvascular obstruction /no-reflow(CMVO/NR) is a predictor of long-term mortality in survivors of ST elevation myocardial infarction (STEMI) underwent primary percutaneous coronary intervention (PPCI). OBJECTIVE To identify risk factors of CMVO/NR. METHODS Totally 2384 STEMI patients treated with PPCI were divided into two groups according to thrombolysis in myocardial infarction(TIMI) flow grade:CMVO/NR group(246cases,TIMI 0-2 grade) and control group(2138 cases,TIMI 3 grade). We used univariable and multivariable logistic regression to identify risk factors of CMVO/NR. RESULTS A frequency of CMVO/NR was 10.3%(246/2384). Logistic regression analysis showed that the differences between the two groups in age(unadjusted odds ratios [OR] 1.032; 95% CI, 1.02 to 1.045; adjusted OR 1.032; 95% CI, 1.02 to 1.046 ; P <0.001), periprocedural bradycardia (unadjusted OR 2.357 ; 95% CI, 1.752 to 3.171; adjusted OR1.818; 95% CI, 1.338 to 2.471 ; P <0.001),using thrombus aspirationdevices during operation (unadjusted OR 2.489 ; 95% CI, 1.815 to 3.414; adjusted OR1.835; 95% CI, 1.291 to 2.606 ; P =0.001),neutrophil percentage (unadjusted OR 1.028 ; 95% CI, 1.014 to 1.042; adjusted OR1.022; 95% CI, 1.008 to 1.036 ; P =0.002) , and completely block of culprit vessel (unadjusted OR 2.626; 95% CI, 1.85 to 3.728; adjusted-OR 1.656;95% CI, 1.119 to 2.45; P =0.012) were statistically significant ( P <0. 05). The area under the receiver operating characteristic curve was 0.6896 . CONCLUSIONS Age , periprocedural bradycardia, using thrombus aspirationdevices during operation, neutrophil percentage ,and completely block of culprit vessel may be independent risk factors for predicting CMVO/NR.

Abstract Background In the region of South Limburg, the Netherlands, a shared ST-elevation myocardial infarction (STEMI) networking system (SLIM network) was implemented. During out-of-office hours, two percutaneous coronary intervention (PCI) centres—Maastricht University Medical Centre and Zuyderland Medical Centre—are supported by the same interventional cardiologist. The aim of this study was to analyse performance indicators within this network and to compare them with contemporary European Society of Cardiology guidelines. Methods Key time indicators for an all-comer STEMI population were registered by the emergency medical service and the PCI centres. The time measurements showed a non-Gaussian distribution; they are presented as median with 25th and 75th percentiles. Results Between 1 February 2018 and 31 March 2019, a total of 570 STEMI patients were admitted to the participating centres. The total system delay (from emergency call to needle time) was 65 min (53–77), with a prehospital system delay of 40 min (34–47) and a door-to-needle time of 22 min (15–34). Compared with in-office hours, out-of-office hours significantly lengthened system delays (55 (47–66) vs 70 min (62–81), p < 0.001), emergency medical service transport times (29 (24–34) vs 35 min (29–40), p < 0.001) and door-to-needle times (17 (14–26) vs 26 min (18–37), p < 0.001). Conclusions With its effective patient pathway management, the SLIM network was able to meet the quality criteria set by contemporary European revascularisation guidelines.
