The prevalence, incidence, risk factors and prognosis of silent myocardial infarction are less well known than those of silent myocardial ischaemia. The aims of this article are to evaluate the prevalence and incidence of silent myocardial infarction in subjects with or without a history of cardiovascular disease and in diabetic patients, and to identify potential risk factors and estimate prog...
End-stage renal disease (ESRD) patients receiving maintenance hemodialysis and suffering from coronary artery disease (CAD) often receive doses of calcium channel antagonists that are too low. This may be the result of physician's desire to avoid adverse side effects during hemodialysis. The aim of this study was the assessment of the safety and efficacy of incremental doses of diltiazem for th...
The heart is extensively innervated and its performance is tightly controlled by the nervous system. Cardiac innervation density varies in diseased hearts leading to unbalanced neural activation and lethal arrhythmia. Diabetic sensory neuropathy causes silent myocardial ischemia, characterized by loss of pain perception during myocardial ischemia, which is a major cause of sudden cardiac death ...
OBJECTIVES We tested the hypothesis that psychological stress alters plasma levels of opioid peptides and that these plasma levels are related to pain perception in patients with coronary artery disease. BACKGROUND Public speaking psychological stress has previously been shown to be associated with silent ischemia. METHODS After instrumentation and a 30-min rest period, venous blood samples...
INTRODUCTION Silent ischemia is an asymptomatic form of myocardial ischemia, not associated with angina or anginal equivalent symptoms, which can be demonstrated by changes in ECG, left ventricular function, myocardial perfusion, and metabolism. The aim of this study was to evaluate the prevalence of silent myocardial ischemia in a group of patients with asymptomatic carotid stenosis. METHODS...
The extent of abnormally perfused myocardium was compared in patients with and without chest pain during treadmill exercise from a large, relatively low-risk consecutive patient population (n=356) referred for quantitative thallium-201 single-photon emission computed tomography (SPECT). All patients had concurrent coronary angiography. Patients were excluded if they had prior coronary angioplas...
chest pain group. 3) Effective treatment: The efficacy of three standard antianginal drugs on silent myocardial ischemia was studied in 43 patients with EA using Holter monitoring. Antianginal drugs used were long-acting isosorbide dinitrate 40-80 mg/day for nitrates (17 patients), diltiazem 90-180 mg/day for calcium antagonists (13 patients), propranolol 30-60 mg/day or metoprolol 60-120 mg/da...
