Prevalence of severely impaired left ventricular ejection fraction after reperfused ST-elevation myocardial infarction

Abstract

Our data demonstrate that the incidence of severely impaired LV function 53 ± 19 days after a STEMI treated with PCI is low. A severely depressed LVEF early after STEMI was present in 10% of all patients. Only 39% of these patients had a persistently impaired LVEF during follow-up. These findings support an expectant strategy before considering primary preventive ICD implantation after STEMI.

Prediction of arrhythmic events by Wedensky modulation in patients with coronary artery disease

“…Therefore, in the authors' opinion, the present study adds to current literature. Test characteristics of the WMI RT in the present study were comparable to other risk predictors in clinical use for SCD risk stratification [7][8][9][10][11][12]. Test characteristics found for LVEF in the present study were similar to those found for LVEF in previous studies [7][8][9][10][11][12].…”

“…Currently, LVEF is the most widely used single predictor because it was evaluated in most of the clinical trials [1][2][3]. However, test characteristics of LVEF for SCD prediction are far from perfect and LVEF determination lacks precision [7][8][9][10][11][12]. Determination of the Wedensky modulation index (WMI) is a novel and innovative technology for SCD prediction.…”

Clinical profile of patients with acute coronary syndrome with special reference to diabetes mellitus

“…15 41% patients complained about radiation to left upper limb, 5% to both upper limb, 5% to epigastria and 4% to neck and jaw (Table 19) whereas study done by Muhammad AM, Shahzad AK, Sohail S, Ijaz ULHT has shown that radiation of chest pain to shoulder, neck and jaw was seen in 75 (22.7%) whereas in 42 (12.7%) patients pain radiated to both side of the chest, 55 (16.6%) patients had chest pain radiation to chest, shoulder, upper arm and ulnar side of the left forearm and chest pain radiation to interscapular region along with both side of the chest was present in 10 (3.0%) patients, only in 11 (3.3%) patients pain radiated only to left side of the chest. 15 Mean ejection fraction in STEMI was 41.73%, NSTEMI was 40.75% and 57.10% in patients with unstable angina (Table 20 18 In our study population we found that 55.56% were having normal coronary arteries, 76.47% were having single vessel disease, 67.39% patients were having double vessel disease and 0nly 87.50% patients were having triple vessel disease among patients with diabetes mellitus. Whereas in study done by Natali A, Vichi S, Landi P, Severi S, L'Abbate A, Ferrannini E. (Diabetologia 2000) found abnormal coronary arteries more frequently in diabetic patients than in non-diabetes patients (85% vs. 67%, P <0.0001), the excess being explained by prevalence of three vessel disease (36% vs. 17%, P <0.0001).…”

Frequency of Multivessel Severe Coronary Artery Disease in Patients With Non-ST Segment Elevation Myocardial Infarction Having Markedly Raised Cardiac Troponin T

“…MVCAD was noted in 107 (32.82%) patients, however there was no MVCAD in 219 (67.18%) patients in our study. Altmann et al in their study have shown the frequency of MVCAD in 54% patients with NSTEMI [ 16 ]. Another study by Qadir et al, which included 230 NSTEMI patients, found that in 111 patients with cardiac troponin T levels ≤10 folds upper limit of normal, 25 (22.52%) had single vessel, 40 (36%) had two vessel and 34 (30.6%) had three vessel significant CAD, whereas in 119 patients with cardiac troponin T levels >10 folds upper limit of normal, 23 (19.3%) had single vessel, 37 (31.1%) had two vessel and 55 (46.2%) had three vessel significant CAD [ 17 ].…”
