BACKGROUND Supraventricular tachyarrhythmias are common after open heart surgery. Possible causative factors for these arrhythmias include operative trauma, atrial ischemia, electrolyte imbalances, pericardial irritation, and excess catecholamines. Two agents commonly used to control ventricular rate in atrial fibrillation or atrial flutter (AF/AFL) are beta-blockers and calcium channel blocker...
OBJECTIVES We compared the effects of five pharmacologic regimens on the circadian rhythm and exercise-induced changes of ventricular rate (VR) in patients with chronic atrial fibrillation (CAF). BACKGROUND Systematic comparison of standardized drug regimens on 24 h VR control in CAF have not been reported. METHODS In 12 patients (11 male, 69+/-6 yr) with CAF, the effects on VR by 5 standar...
Calcium entry blockers, particularly diltiazem, have been shown to lower not only systemic blood pressure but also improve proteinuria in non-insulin-dependent diabetic patients. The presence of proteinuria is attributed to the loss of glomerular heparan sulfate, which confers a negative charge on the basement membrane. In the present study, we evaluated the efficacy of diltiazem in lowering bl...
BACKGROUND TRUS-guided needle biopsy of the prostate gland is the current standard method used for diagnosis of prostate cancer. Pain control during this procedure is through the use of i.v. sedation or local anaesthetic (LA), depending on clinician preference. OBJECTIVES The aim of this study was to evaluate the effectiveness of intrarectal lidocaine, lidocaine-diltiazem and lidocaine-meperi...
Role of L-type calcium channels on yohimbine-precipitated clonidine withdrawal in vivo and in vitro.
This study was designed to elucidate the possible participation of L-type calcium channels in the expression of clonidine-withdrawal precipitated by yohimbine in clonidine-dependent animals. Mice implanted for 5 days with osmotic minipumps containing the alpha 2-adrenoceptor agonist clonidine showed symptoms of a withdrawal syndrome (jerks, headshakes, defecations and weight loss) when yohimbin...
The effects of oral diltiazem (360 mg/day) on exercise tolerance, left ventricular performance, and plasma lactate and catecholamine levels were studied in 13 patients with atherosclerotic coronary artery disease in a placebo-controlled, randomized, double-blind protocol. Exercise duration to the onset of ischemic ST segment depression, time to angina pectoris, and time to peak exercise improve...
Serial changes in myocardial parameters related to non-insulin-dependent diabetes mellitus were investigated in DDY mice (control), untreated KK mice, and KK mice treated with diltiazem (150 micrograms/kg body weight, KKd1: or 300 micrograms/kg body weight diltiazem, KKd2). The isozyme ratio of lactate dehydrogenase (LDH) [(LDH1+LDH2)/(LDH4+LDH5)] was used as an index of aerobic metabolism of m...
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...
A 59 year old man with ischaemic heart disease, developed the clinical and electromyographic changes of the Lambert-Eaton myasthenic syndrome after taking calcium antagonist, diltiazem. The symptoms appeared periodically with a rise and fall in serum level of diltiazem. Extensive search was made for systemic neoplasms and autoimmune diseases without success. Serum antibody to voltage operated c...
