digitalis/headache

The administration of digitalis glycosides causes a variety of extracardiac effects. In both normal human subjects and in other species, digitalis increases smooth muscle tone of resistance and capacitance vessels. The vasoconstriction is mediated, in part, by a direct action of these glycosides on

In 1148 cases the serum digoxin concentration (SDC) was correlated with the extracardiac signs of digitalis intoxication. There is a considerably overlap of SDC levels of patients with and without extracardiac signs of toxicity even though the mean SDC's of these two groups differ significantly. An

Over the last ten years the efficacy of lithium salts in cluster headache has been well demonstrated. Our patient, who had been suffering from cluster headache for approximately 30 years, had been in haemodialysis treatment for the last ten years for chronic renal failure. Moreover, he was affected

A 45 years old male presented to the emergency department with palpitations, headache and apprehension. His electrocardiogram revealed bidirectional ventricular tachycardia. He remained vitally stable and responded to intravenous beta-blocker. Initially digitalis toxicity was suspected but history

OBJECTIVE Evaluation of the clinical effects of captopril addition to the conventional therapy of functional class II and III (NYHA) congestive heart failure (CHF). METHODS One hundred and fifteen patients with CHF, 46 (40%) class II and 69 (60%) class III, on conventional treatment (digitalis and

BACKGROUND This multicenter trial was conducted to determine the efficacy and safety of pimobendan, an inotropic agent with calcium-sensitizing properties and activity as a phosphodiesterase inhibitor, in patients with heart failure. RESULTS One hundred ninety-eight ambulatory patients with symptoms

Due to the age-associated increase in morbidity, many elderly subjects are in need of multiple drug treatment. Multimedications, however, carry a high risk for adverse drug reactions (ADR) and drug-drug interactions (DDI). This risk is especially increased in very old patients since age and

OBJECTIVE To assess the character and cause of photopsias in vitreoretinal patients. METHODS Cross-sectional study. METHODS A total of 169 consecutive patients (217 eyes) with vitreoretinal disease presenting with a history of photopsias. METHODS A total of 217 eyes with photopsias in 169 patients

The Cardiac Arrhythmia Pilot Study tested the feasibility of performing a large-scale study to evaluate the effect of therapy of ventricular arrhythmias after acute myocardial infarction (AMI). Ten clinical sites identified patients with greater than or equal to 10 ventricular premature complexes

Nitrates, which have been used for more than a century, are the second oldest drug (after digitalis alkaloids) in the cardiological pharmacological arsenal. However, several facets of their mode of use still remain controversial. Their vasodilator and arteriolodilator action (especially in coronary
