OBJECTIVE Biochemical markers are useful for the prediction of future cardiovascular events in patients with non-ST-segment elevation acute coronary syndrome (ACS). The independent as well as the combined prognostic value of elevated troponin-T, high-sensitivity C-reactive protein (hs-CRP), and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) on the(More)
This report describes a modified cephalic vein guide wire technique used for implantation of 18 consecutive pacemakers using bipolar leads. The modified technique appears to be a safe and simple procedure for single chamber permanent pacing. Its use may also be extended in implanting dual chamber pacemakers.
Blood samples from 39 patients with acute myocardial infarction and 15 healthy controls were analysed for serum and platelet sialic acid. Serum sialic acid levels in patients with acute myocardial infarction were significantly higher than controls (mean 2.7±0.46 μmol/ml Vs. 1.91±0.17 μmol/ml respectively). Levels of serum orosomucoid, an acute phase(More)
Patients of chronic exudative pericardial effusion are frequently treated with antitubercular treatment on presumptive grounds in developing countries, in a hope to prevent constrictive pericarditis. To assess the impact of antitubercular treatment on development of constrictive pericarditis in chronic large exudative pericarditis effusion of undetermined(More)
BACKGROUND AND HYPOTHESIS There is no method available to predict the relative antianginal efficacy of beta blockers and calcium-channel antagonists. The present study was undertaken to assess the role of silent ischemic interval (SII) on exercise treadmill test (ETT) as a predictor of response to therapy with metoprolol and diltiazem in patients with(More)
Presence of multivessel coronary artery disease (MVD) identifies a high risk subgroup after acute myocardial infarction (AMI). Dobutamine stress echocardiography (DSE) has recently emerged as a promising non invasive test to detect the presence and extent of coronary artery disease. Forty six consecutive patients (38 males, 8 females; mean age 48.6 +/- 10.4(More)
A case of systemic hypotension with volume depletion not responding to intravenous fluids was found to have features of cardiac tamponade on two-dimensional (2-D) echocardiography. Intracardiac pressures were normal on cardiac catheterization. An interesting observation was the presence of left ventricular (LV) collapse on 2-D echocardiography. To the(More)
OBJECTIVE Inflammation has been proposed as one of the factors responsible for the development of coronary artery disease (CAD) and high sensitivity C-reactive protein (hs CRP) at present is the strongest marker of inflammation. We did a study to assess the correlation of hs-CRP with socio-economic status (SES) in patients of CAD presenting as acute(More)
BACKGROUND Left ventricular pacing is increasingly being used as a part of biventricular pacing in congestive heart failure but data on safety, feasibility, reliability and lead maturation are sparse. METHODS AND RESULTS Seventeen patients (13 males and 4 females) with persistent symptomatic degenerative complete heart block underwent temporary left(More)
