Do non-potassium-sparing diuretics increase the risk of sudden cardiac death in hypertensive patients? Recent evidence.
Whether non-potassium-sparing diuretics (NPSD) increase the risk of sudden cardiac death in hypertensive patients has been vigorously debated. Diuretic-induced potassium or magnesium depletion leading to cardiac arrhythmias has been suggested as the underlying mechanism. A clear dose-response relationship between NPSD and the reduction in serum K+ exists. Data regarding serum Mg++ and intracell...
متن کاملDiuretics in the treatment of hypertension. Part 2: loop diuretics and potassium-sparing agents.
INTRODUCTION Diuretics enhance the renal excretion of Na(+) and water due to a direct action at different tubular sites of the nephron where solute re-absorption occurs. AREAS COVERED This paper focuses on the mechanism of action, pharmacodynamics, antihypertensive effects, adverse effects, interactions and contraindications of loop diuretics and potassium-sparing agents (including mineraloco...
متن کاملDiuretics and risk of arrhythmic death in patients with left ventricular dysfunction.
Background-Treatment with diuretics has been reported to increase the risk of arrhythmic death in patients with hypertension. The effect of diuretic therapy on arrhythmic death in patients with left ventricular dysfunction is unknown. Methods and Results-We conducted a retrospective analysis of 6797 patients with an ejection fraction <0.36 enrolled in the Studies Of Left Ventricular Dysfunction...
متن کاملArrhythmogenic potential of diuretic induced hypokalaemia in patients with mild hypertension and ischaemic heart disease.
In view of evidence suggesting an association of mild hypokalaemia with cardiac arrhythmia, the arrhythmogenic potentials of potassium losing and potassium sparing diuretic treatments were compared in a controlled prospective crossover study of 10 patients with mild hypertension and ischaemic heart disease. Mean (SEM) plasma potassium was 4.3(0.06) mmol/l and 3.3(0.07) mmol/l after potassium sp...
متن کاملAntihypertensive drug use. Trends in the United States from 1973 to 1985.
Hypertension, a major public health problem, often requires drug therapy. We examined trends in outpatient antihypertensive drug use in the United States from 1973 to 1985. The numbers of prescriptions and the diagnostic and drug treatment information were obtained from the National Prescription Audit (Ambler, Pa, IMS America, 1985) the National Disease and Therapeutic Index (Ambler, Pa, IMS Am...
