BACKGROUND: Chest pain/discomfort (CP) is the hallmark symptom of acute myocardial infarction (MI), but some patients with MI present without CP. We hypothesized that MI type (ST-segment elevation MI [STEMI] or non-STEMI [NSTEMI]) may be associated with the presence or absence of CP. METHODS: We investigated the association between CP at presentation and MI type, hospital care, and mortality among 1,143,513 patients with MI in the National Registry of Myocardial Infarction (NRMI) from 1994 to 2006...

BACKGROUND: There is a paucity of randomized trials regarding diagnostic testing in women with suspected coronary artery disease (CAD). It remains unclear whether the addition of myocardial perfusion imaging (MPI) to the standard ECG exercise treadmill test (ETT) provides incremental information to improve clinical decision making in women with suspected CAD. METHODS AND RESULTS: We randomized symptomatic women with suspected CAD, an interpretable ECG, and ≥5 metabolic equivalents on the Duke Activity Status Index to 1 of 2 diagnostic strategies: ETT or exercise MPI...

Four male subjects exercised on cycle ergometers at 40-51% of maximal aerobic power in the upright and supine positions at air temperatures of 15, 25, and 40 degrees C. Esophageal temperature (Tes) was measured at heart level, and mean skin temperature was computed from a weighted average of eight skin temperature measurements. Forearm blood flow (ABF) was measured by venous occlusion plethysmography, and cardiac output was measured by a CO2 rebreathing technique. At air temperatures of 15 and 25 degrees C, cardiac stroke volume was slightly lower during upright exercise than it was during supine exercise, as was ABF at a given Tes...

The current worldwide explosive increase in the numbers of older persons is unprecedented in history. In the 1990s and beyond, the preponderance of patients with cardiovascular illness will be elderly, with a substantial subset among the frail elderly, 85 years old and older. Cardiovascular disease remains the leading cause of death and disability in this population, and cardiovascular risk increases steadily with age. Pascal defined old age as "just a time that is farther from the beginning and nearer to the end...

At any given environmental and mean skin temperature, exercise brings about an increase in internal body temperature and skin blood flow. At high environmental temperatures, when skin temperature is elevated, skin blood flow at any given internal temperature reaches higher levels than at cooler skin temperatures. Increased cutaneous blood flow serves to deliver metabolic heat from the core to the skin, where the heat is lost to the environment by convective, radiative, and evaporative mechanisms. However, at high levels of skin blood flow, peripheral vascular pooling and fluid losses by filtration lead to reduced central venous pressure...

Three relatively fit subjects performed duplicate 20- to 25-min cycle ergometer exercise bouts at moderate and heavy intensities (40% and 70% Vo2 max) in ambient temperatures of 20, 26, and 36 degrees C. They approached a steady state in internal body temperature (Tes) in all but the heavy exercise in the heat, where Tes rose consistently, averaging 38.84 degrees C at the termination of exercise. Cardiac output (Q), estimated by a rebreathing technique, was proportional to Vo2 and independent of the body temperatures, except during the lower exercise intensity in the heart, where Q averaged 1...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
