BACKGROUND Deaths from diseases of the circulatory system and the seasonality of deaths from these causes fell sharply between 1995 and 2005 among older age groups in Ireland. We examine whether a structural break occurred in deaths from circulatory causes in Ireland between 1995 and 2005 and test whether this can be statistically accounted for by cardiovascular prescribing during the same peri...
This study examined the effects of different types of calcium channel antagonists on renal haemodynamics and natriuresis. The intravenous infusion of nifedipine (L-type blocker), efonidipine (L/T-type blocker) or mibefradil (predominant T-type blocker) into anaesthetized dogs elicited similar, albeit modest, reductions in blood pressure. Nifedipine (1 microgram.min(-1).kg(-1)) increased renal p...
OBJECTIVE To provide a management approach for adults with calcium channel blocker poisoning. DATA SOURCES, STUDY SELECTION, AND DATA EXTRACTION Following the Appraisal of Guidelines for Research & Evaluation II instrument, initial voting statements were constructed based on summaries outlining the evidence, risks, and benefits. DATA SYNTHESIS We recommend 1) for asymptomatic patients, obse...
Lidoflazine, a calcium channel blocker, was administered to dogs following twelve minutes of cerebral ischemia, induced by aortic cross-clamping. The effects of lidoflazine (1 mg/kg i.v.) on cerebral blood flow following ischemia was studied in 15 anesthetized, mechanically ventilated dogs. Cerebral blood flow was measured with the radiolabelled microsphere technique before and 10, 30, 60, 90 a...
10.2217/14750708.4.1.31 © 20 Despite the availability of numerous antihypertensive agents, many patients with hypertension fail to achieve the blood pressure goals set out in current guidelines. These patients remain at a high risk of cardiovascular morbidity and mortality and require effective treatment options to reduce that risk. Current guidelines recognize that many patients require multip...
Amlodipine, a dihydropyridine calcium channel blocker, is commonly prescribed for the treatment of hypertension. Ingestion of an overdose leads to severe hypotension; if the hypotension is not treated, death may be imminent. Conventional and unconventional interventions were used to treat an adolescent who ingested a life-threatening dose of amlodipine. Severe hypotension resistant to conventio...
Intervention: rate control (n = 256) or rhythm control (n = 266). Rate control included use of digitalis, a non-dihydropyridine calcium channel blocker, and a b blocker, alone or in combination. Target resting heart rate was ,100 beats/minute. Patients in the rhythm control group received serial electrical cardioversion and serial antiarrhythmic drugs using sotalol, 160– 320 mg/day, as the firs...
The spontaneous firing patterns of striatal cholinergic interneurons are sculpted by potassium currents that give rise to prominent afterhyperpolarizations (AHPs). Large-conductance calcium-activated potassium (BK) channel currents contribute to action potential (AP) repolarization; small-conductance calcium-activated potassium channel currents generate an apamin-sensitive medium AHP (mAHP) aft...
While it is relatively uncommon, an overdose of calcium-channel blockers, beta blockers, or digoxin has a significant morbidity and mortality rate, and its management can be complex. Digoxin toxicity can present with an acute overdose or as chronic toxicity while a patient is on therapeutic dosing, which has implications for diagnosis and management. While the patient's specific clinical presen...
