Cesium-129 is concentrated in the myocardium after intravenous administration permitting myocardial imaging. The dosage used was 2-2.5 mCi in dogs and 3-4 mCi in patients. Four or more views with 200,000 counts per view were obtained 30 to 90 minutes after administration. Control images were obtained in 30 dogs. In two dogs anatomic landmarks were obtained using technetium-99m markers. In 24 do...

ventricular MI suppresses this ST segment elevation in the precordial leads and yields an ST segment elevation in leads II, III, and aVF.2-4 Massive STsegment elevation in precordial and inferior leads in RVMI has also been observed but is extremely rare.5 Thus, ST elevation in precordial leads should not exclude an infarction of the right ventricle that demands a treatment different from that ...

This case report concerns a 68 year old male with, type 2 diabetes, stage 3 hypertension, hypercholesterolemia, myocardial infarction (MI) 20 years ago. He was admitted to the catheterization laboratory with suspected acute inferior wall MI. Angiography of pulmonary arteries revealed massive thrombosis.

OBJECTIVE The initial site of myocardial infarction (MI) may influence the prevalence of ventricular late potentials (VLP), high-frequency signals, due to the time course of ventricular activation. The prevalence of VLP in a period of more than 2 years after acute MI was assessed focusing on the initially injured wall. METHODS The prevalence of VLP in a late phase after MI (median of 924 days...

A 36-year-old man with classic angina pectoris had marked ST-segment elevation (STE) in the inferior leads on stress-testing in the absence of chest pain. There was no evidence of previous myocardial infarction (MI). Selective coronary arteriography delineated severe obstructions in the right coronary artery (RCA) with additional left circumflex coronary artery (LCx) obstruction. Left ventricul...

BACKGROUND Chronic ischemic mitral regurgitation (CIMR) is associated with heart failure that continues unabated whether the valve is repaired, replaced, or ignored. Altered left ventricular (LV) torsion dynamics, with deleterious effects on transmural gradients of oxygen consumption and diastolic filling, may play a role in the cycle of the failing myocardium. We hypothesized that LV dilatatio...

Experimental coronary occlusion is accompanied by an acute impairment of the baroreceptorheart rate reflex. This study was planned to determine whether this impairment also occurs in humans. In 30 patients admitted to a coronary care unit for an anterior (n= 14) or inferior (n=16) transmural myocardial infarction (MI), we measured 1) the increase in RR interval induced by stimulating carotid ba...

To know the relationship between positive ventricular late potentials (LP) and occurrence of ventricular tachycardia (VT), signal-averaged electrocardiogram (SAECG) was recorded in 214 patients with myocardial infarction (MI). According to the time course of SAECG recording after the onset of MI, the subjects were divided into three groups; acute MI (AMI) group (onset-2nd week, n = 148), recent...

OBJECTIVE To study the effect of thrombolytic therapy in term of success and failure on the type of ST elevation MI, using streptokinase. MATERIAL AND METHODS This was a comparative study, conducted at Department of Cardiology, Lady Reading Hospital, Peshawar, from October 2006 to October 2007. Patients with first acute myocardial infarction were divided into group A (successful thrombolysis)...
