OBJECTIVES Our aim was to look at the clinical features and long-term follow-up of seven patients without coronary artery disease, who had a history of life-threatening ventricular arrhythmias due to coronary spasm. BACKGROUND Arrhythmic cardiac arrest due to isolated coronary spasm is rare, and there is limited information on the patients affected by this entity alone. METHODS The seven pa...

Bee stings are commonly encountered worldwide. Various manifestations after bee sting have been described 1 . Local reactions are common. Unusually, manifestations like vomiting, diarrhoea, dyspnoea, generalised oedema, acute renal failure, hypotension and collapse may occur. Rarely vasculitis, serum sickness, neuritis and encephalitis have been described which generally develop days to weeks a...

Background—Intracoronary brachytherapy is effective in preventing restenosis after coronary interventions. However, in vitro and animal studies have shown that irradiation produces immediate and sustained endothelial dysfunction. This study assesses the clinical relevance of impaired vasomotoric function induced by brachytherapy. Methods and Results—We analyzed the occurrence of postradiation c...

UNLABELLED Coronary artery disease (CAD) remains the major cause of mortality and morbidity in the United States despite significant advances for the prevention and treatment of CAD. Coronary artery spasm causing demand-supply mismatch with coronary ischemia can mimic CAD, resulting in unnecessary interventions. Left main coronary artery spasm, in particular, is a rare entity with only a few ca...

Myocardial infarction occurring in young people with angiographically normal coronary arteries is well described but the pathophysiology of this condition remains unknown. Coronary artery spasm in association with thrombus formation and minimal atheromatous disease or spontaneous coronary artery dissection are possible causes. Two young men presented with severe chest pain after acute alcohol i...

BACKGROUND Coronary artery spasm is a transient narrowing of coronary arteries that slows or stops blood flow through the artery. CASE REPORT We present a 42-year-smoker man without any medical problem who developed syncope. Coronary angiography revealed diffuse significant narrowing of proximal left anterior descending artery (LAD), 90% osteal stenosis of large obtuse marginal (OM), 90% diff...
