Exercise-induced myocardial ischemia detected by cardiopulmonary exercise testing.
Cardiopulmonary exercise testing (CPET) is a well-accepted physiologic evaluation technique in patients diagnosed with heart failure and in patients presenting with unexplained dyspnea on exertion. Several variables obtained during CPET, including oxygen consumption relative to heart rate and work rate provide consistent, quantitative patterns of abnormal physiologic responses to graded exercis...
متن کاملExercise-induced myocardial ischaemia detected by cardiopulmonary exercise testing.
BACKGROUND The objective of the study was to identify the parameter(s) of cardiopulmonary exercise testing (CPET) that can detect exercise-induced myocardial ischaemia (EIMI), and to determine its diagnostic accuracy for identifying patients with coronary artery disease (CAD). METHODS AND RESULTS We prospectively studied 202 consecutive patients (173 men, 29 women, mean age 55.7+/-10.8 years)...
متن کاملThe invasive cardiopulmonary exercise test.
A 71-year-old man was evaluated for a chief complaint of progressive dys-pnea on exertion over the previous 5 years. The patient's medical history is significant for revascularized coronary artery disease, left diaphragmatic paresis, systemic hypertension, and obesity. His medications included aspirin 81 mg daily, metoprolol succinate 100 mg daily, lisinopril 10 mg daily, and simvastatin 20 mg ...
متن کاملCaffeine decreases exercise-induced myocardial flow reserve.
OBJECTIVES We studied the acute effect of caffeine on myocardial blood flow (MBF) at rest and exercise in healthy volunteers at normoxia and during acute exposure to simulated altitude. BACKGROUND Caffeine is a widely consumed stimulant, although its cardiovascular safety remains controversial and its effect on MBF is unknown. METHODS 15O-labeled H2O and positron emission tomography (PET) w...
متن کاملCardiopulmonary exercise testing diagnosis of myocardial suppression.
was carried out. The patient’s condition started deteriorating immediately and he became more tachypnoeic and dyspnoeic, with an oxygen saturation of 88%. A chest drain was inserted on the left side, but the patient became increasingly hypoxic, had seizures and progressed to a Pulseless Electrical Activity cardiac arrest. Cardiopulmonary resuscitation was started and the trachea intubated. With...
