Background: Left ventricular dysfunction is the single strongest predictor of mortality and one of the most frequent and deadly complication following coronary artery diseases. Aim: This   work   aims   to   study   and  explore  the  left  ventricle  ejection  fraction  improvement  after revascularization  with percutaneous coronary intervention (PCI) and the predictive factors for left ventricle ejection fraction improvement. Methods: One hundred patients with ischemic (HFrEF) who had complete revascularization with percutaneous coronary intervention (PCI), had survived at least 90 days and had undergone echocardiography review. The study duration was 1 year from April 2019 to May 2020. Result: We focused on a group of the common possible predictive factors affecting left ventricular improvement. Gender (male), CKD, DM, number of affected vessel(single vessel disease), CTO lesion, heart rate, ECG findings, presence of anginal pain, presence of dyspnea , usage of medications ( ACEI and Clopidogrel),hyper urecemia and the time between presentation of complaints and PCI were correlated with improvement of left ventricular function after revascularization by PCI. Conclusion: Time between appearance of symptoms and PCI was found to be independent predictor of LV EF improvement after revascularization. Other predictors were Male gender, DM, CKD, normal ECG finding ,absence of hyper urecemia, slower heart rate ,presence of chest pain and dyspnea , absence of CTO lesion , single vessel affection and administration of ACEI and Clopidogrel.

Background: Aim of the study was to evaluate the primary procedural success of percutaneous coronary intervention of unprotected left main coronary artery stenosis using either Bare-metal stents or drug eluting stent. Methods: Total 33 patients were enrolled in this very preliminary non-randomized prospective cohort study. Among them, Male: 25 and Female: 8. Total 35 stents were deployed. Mean age were for Male: 59 yrs, for Female: 62 yrs. Associated coronary artery diseases risk factors were dyslipidemia, High Blood pressure, Diabetes Mellitus, Positive family history for coronary artery diseases and smoking. Results: Among the study group; 26 (78%) were Dyslipidemic, 24(70%) were hypertensive; 17 (51.5%) patients were Diabetic, 11(33%) were smoker and 7(21%) patients had family history of Ischaemic heart disease. Female patients were more obese (BMI M 26: F 27) and developed coronary artery diseases in advance age. Common stented territory were left main: 20 (60%), Left main to left anterior descending artery 7 (22%) and Left main to left circumflex artery 6 (18%). Average length and diameter of stent was 3.5 and 18 mm respectively. Stent used: Bare Metal Stent 5 (15%), Drug Eluting Stent: 28 (85%). Among the different Drug Eluting Stents, Everolimus eluting stents were 11 (39.3%), Sirolimus eluting 10(35.7%), Paclitaxel eluting 3 (10.7%), Biolimus eluting 3 (10.7%) and Zotarolimus eluting1 (3.6%). In the present study, overall survival outcome was 94% (31 patient), mortality of cardiac cause 3% (1 patient) and 1 patient (3%) died of hepatocellular carcinoma. Conclusion: Our study has shown that percutaneous coronary intervention of the unprotected left main is a safe and effective alternative to Coronary Artery Bypass Graft (CABG).

Abstract Background The aim of this study was to determine the difference in effects of beta-blockers on long-term clinical outcomes between ischemic heart disease (IHD) patients with mid-range ejection fraction (mrEF) and those with reduced ejection fraction (rEF). Methods Data were assessed of 3508 consecutive IHD patients who underwent percutaneous coronary intervention (PCI) between 1997 and 2011. Among them, 316 patients with mrEF (EF = 40–49%) and 201 patients with rEF (EF < 40%) were identified. They were assigned to groups according to users and non-users of beta-blockers and effects of beta-blockers were assessed between mrEF and rEF patients, separately. The primary outcome was a composite of all-cause death and non-fatal acute coronary syndrome. Results The median follow-up period was 5.5 years in mrEF patients and 4.3 years in rEF patients. Cumulative event-free survival was significantly lower in the group with beta-blockers than in the group without beta-blockers in rEF (p = 0.003), whereas no difference was observed in mrEF (p = 0.137) between those with and without beta-blockers. In the multivariate analysis, use of beta-blockers was associated with reduction in clinical outcomes in patients with rEF (hazard ratio (HR), 0.59; 95% confidence interval (CI), 0.36–0.97; p = 0.036), whereas no association was observed among those with mrEF (HR 0.74; 95% CI 0.49–1.10; p = 0.137). Conclusions Our observational study showed that use of beta-blockers was not associated with long-term clinical outcomes in IHD patients with mrEF, whereas a significant association was observed in those with rEF.

Background: The treatment of LMCAD has shifted from coronary artery bypass grafting (CABG) to Percutaneous coronary intervention (PCI). However, data on long-term outcomes of PCI for LMCA disease, especially in patients with acute coronary syndrome (ACS) remains limited and conicting. This study aims to nd the association of the immediate and 4-year mortality in ACS patients with LMCA disease treated by PCI based on ejection fractions at admission. Methods: A retrospective analytical study was conducted. Patients were divided at admission into those with reduced left ventricular ejection fraction and those with preserved ejection fraction. Results: Forty (58.8%) of the patients presented with preserved EF. The mean age of the patients was 71.6±7.1 years. The mean LVEF of the preserved group was 61.6±4.3% and signicantly higher than that of the reduced group. Age and cardiovascular risk factor prole was similar between the two groups. Patients with reduced ejection fraction had signicantly higher levels of serum creatinine and signicantly lower levels of Hb and HDL. Mean hospital stay was signicantly longer for patients with preserved EF. In-hospital deaths were also similar between the two groups. The reduced EF group had a signicantly higher allcause mortality in the 4-year follow-up period. The mean years of follow-up for all participants was 4.2±1.3 years. Conclusion: It was seen that in patients presenting with ACS and undergoing PCI due to LMCAD, LVEF at admission, singly and in in multivariate regression is an important predictor of in hospital and 4-year mortality

<p><strong>BACKGROUND:<em> </em></strong>There is considerable disagreement over the effects of percutaneous coronary intervention (PCI) on left ventricular diastolic function that has necessitated the investigation of diastolic indices. The present study was conducted to evaluate left ventricular diastolic function and its indices, three months after performing the PCI procedure in patients with coronary artery disease (CAD).</p> <p><strong>METHODS:<em> </em></strong>In a quasi-experimental clinical trial study (before and after), 51 patients with CAD scheduled for elective PCI were investigated provided that their Ejection Fraction (EF) was &gt; 30%. Before and three months after PCI, echocardiography was carried out to evaluate left ventricular diastolic indices including the E/Ea as the most important criteria for diagnosis of diastolic heart failure (DHF).<strong></strong></p> <p><strong>RESULTS:<em> </em></strong>Based on the E/Ea indices and after PCI, the number of patients with DHF decreased significantly: 40 patients (78.4%) before PCI versus 28 patients (54.9%) after PCI (p&lt;0.05). The Mean and Standard error of deceleration time (DT), isovolumic relaxation time (IVRT), early diastolic mitral annulus velocity; Ea (E'), E/Ea and left ventricular ejection function (LVEF) indices underwent significant changes. In addition, MVA dur/PVA dur, PVs/PVd, and E/Ea indices had changed significantly after PCI in both genders. However, no significant difference was reported for the other indices.</p> <p><strong>CONCLUSION:<em> </em></strong>The E/Ea ratio as an important criterion for diagnosis of DHF was improved after PCI. Improvement of several other diastolic indices was observed after the PCI procedure. It can be concluded that PCI can be an effective treatment modality in patients with left ventricular diastolic indices.</p>

Background: Patients with complex high-risk coronary anatomy, such as those with a last remaining patent vessel (LRPV), are increasingly revascularized with percutaneous coronary intervention (PCI) in contemporary practice. There are limited data on the outcomes of these high-risk procedures. Methods: We analyzed a large longitudinal PCI cohort (2007–2014, n=501 841) from the British Cardiovascular Intervention Society database. Clinical, demographic, procedural, and outcome data were analyzed by dividing patients into 2 groups; LRPV group (n=2432) and all other PCI groups (n=506 691). Results: Patients in the LRPV PCI group were older, had more comorbidities, and higher prevalence of moderate-severe left ventricular systolic dysfunction. Mortality was higher in the LRPV PCI group during hospital admission (12 % versus 1.5 %, P <0.001), at 30 days (15% versus 2%, P <0.001), and at one-year (24% versus 5%, P <0.001). In a propensity score matching analysis the adjusted risk of mortality during index admission (odds ratio, 2.05 [95% CI, 1.65–2.44], P <0.001), at 30 days (odds ratio, 2.13 [95% CI, 1.78–2.5], P <0.001), at 1 year (odds ratio, 1.81 [95% CI, 1.59–2.03], P <0.001), and in-hospital major adverse cardiovascular events (odds ratio, 1.8 [95% CI, 1.42–2.19], P <0.001) were higher in LRPV PCI group as compared to control group. In sensitivity analyses, similar clinical outcomes were observed irrespective of which major epicardial coronary artery was treated. Conclusions: In this contemporary cohort, patients who had PCI to their LRPV had a higher-risk profile and more adverse clinical outcomes, irrespective of the vessel treated.
