OBJECTIVES In a prospective study we evaluated whether late recanalization of the left anterior descending coronary artery (LAD) affects ventricular volume and function after anterior myocardial infarction. BACKGROUND Persistent coronary occlusion after anterior myocardial infarction leads to ventricular dilation and heart failure. METHODS We studied 73(More)
OBJECTIVE To evaluate the stress-myocardial perfusion pattern in patients with angina, positive exercise test and angiographically smooth coronary arteries (syndrome X). DESIGN Prospective study. PATIENTS AND METHODS Twenty-five consecutive patients (seven males, mean age 54 +/- 8 years) with typical angina, positive exercise test, normal coronary(More)
BACKGROUND Controversial evidence exists as to whether thrombolytic therapy reduces the incidence of left ventricular thrombus in acute myocardial infarction and, if so, how this relates to successful reperfusion. METHODS Four hundred and eighteen consecutive patients underwent echocardiography and coronary angiography within 3 weeks of an acute(More)
Previous studies have shown that adhesion molecules play a crucial role in leukocyte-endothelium interactions that occur during myocardial ischemia and reperfusion. We assessed the plasma levels of the soluble form of E-selectin (sE-selectin) and intercellular adhesion molecule-1 (sICAM-1) in 15 patients with acute myocardial infarction (AMI) and in 15(More)
OBJECTIVE To assess exercise performance and resting left ventricular filling dynamics in patients with syndrome X (SX) in basal conditions and after 10 days treatment with oral atenolol. DESIGN AND PATIENTS Exercise performance was studied and left ventricular filling assessed by Doppler-derived transmitral flow pattern analysis in 22 patients (16(More)
In a patient with sporadic atypical chest pain associated with dyspnea, stress Tc-99m MIBI imaging showed normal perfusion and inferoposterior hypoperfusion on the resting study. Although this reverse perfusion pattern was considered artifactual, the patient later had an acute myocardial infarction involving the same areas. Postinfarction stress Tc-99m MIBI(More)
Development of a perfusion defect on the 201Tl image from exercise to redistribution is referred to as reverse redistribution, a finding which has been previously associated with several conditions. We describe here two cases in which the reverse-redistribution phenomenon, observed in a routine stress-redistribution thallium-201 scan performed because of(More)
AIMS We investigated the ability of T-wave pseudonormalization and ST-segment elevation, which are demonstrated in infarct-related leads during submaximal exercise testing, to predict late recovery of contractile function. METHODS We studied 88 consecutive patients (73 males, mean age 59 +/- 8 years) with anterior infarction, persistent T-wave inversion(More)
Percutaneous renal denervation has emerged as an effective adjunct in the management of resistant hypertension. However, the limits of the renal anatomical criteria that can be successfully treated are still unknown. In this report, we describe the case of a middle-aged man with essential resistant hypertension and two small left accessory renal arteries(More)
