We report a rare presentation of mitral stenosis (MS). MS is a common valvular disease, the first manifestation of which is usually easy fatigability and exertional dyspnea. As the disease progresses in severity, other signs and symptoms appear, such as orthopnea, hemoptysis, and peripheral edema. This is the first report of a case of mitral stenosis presenting with exertional abdominal pain as...

Post-exertional “malaise” is a hallmark symptom of Myalgic Encephalomyelitis (ME) and Chronic Fatigue Syndrome (CFS). Various abnormalities, including abnormal physiological responses to exertion, can account for post-exertional “malaise” and “exercise avoidance”. Since these abnormalities are not observed in sedentary healthy controls, the abnormalities and deviant responses cannot be explaine...

BACKGROUND Genetic polymorphisms may affect the balance between coagulation and fibrinolysis and thereby affect individual vulnerability to acute myocardial infarction (MI) among patients with underlying coronary atherosclerosis. METHODS We enrolled 1375 patients with an initial clinical presentation of coronary disease. We genotyped 49 single nucleotide polymorphisms (SNPs) in 9 coagulation ...

OBJECTIVES Severe damage to skeletal muscle is usually seen in patients with exertional heatstroke. Thirty seven young military recruits with exertional heatstroke in Taiwan from 1992 to 1995 were studied to evaluate changes in muscle pathology and blood lactate with exercise. METHODS A biopsy sample of the vastus lateralis was taken from recruits within 10 days of the initial presentation. R...

BACKGROUND Exertional heat stroke is a devastating condition that can cause significant morbidity and mortality. Rapid cooling is the most effective means of treating heat stroke, but little is published on the safety and logistics of cooling patients on site at a major sporting event. PURPOSE To describe an on-site exertional heat stroke treatment protocol and to compare the outcomes of pati...
