Anaerobic Threshold and Maximal Oxygen Uptake in Patients with Coronary Artery Disease and Stable Angina before and after Percutaneous Transluminal Coronary Angioplasty

“…Exercise was discontinued if the patients experienced one of the following symptoms: subjective exertion, dyspnea, increasing or moderate chest pain, ST-segment depression >0.2 mV with horizontal or descending slope, ST-segment elevation, maximal age-adapted heart rate (200 – age)·0.8, systolic blood pressure >250 mm Hg or diastolic blood pressure >115 mm Hg, a drop in blood pressure or supraventricular and ventricular arrythmias [6]. …”

“…It is indisputable that symptomatic improvement [1, 2]and a better quality of life [3, 4]are achieved by PTCA. Apart from subjective symptoms, temporary myocardial ischemia induces intermittent impairment in diastolic function with enhanced myocardial stiffness [5]and in systolic function [6]with pulmonary congestion [7]. In addition, some investigations have shown that functional capacity [1, 8]is reduced in patients with CAD.…”

Human Paraoxonase1 Gene Polymorphisms and the Risk of Coronary Heart Disease: A Community-Based Study

“…All subjects exercised on an electronically braked cycle ergometer (Case 15, Marquette Electronics, Milwaukee, Wisc., USA) according to a multistage Bruce protocol. Exercise-induced ST-segment changes in the standard leads were defined as a horizontal or downsloping ST-segment depression of at least 1 mm 60 ms after the J point [34]. Complete M-mode and two-dimensional echocardiography as well as Doppler examination were done using commercially available equipment (Vingmed CFM 750 or 800, General Electrics Ultrasound, Horton, Norway).…”

Noninvasive Diagnosis of Coronary Artery Disease: A Comparison between Cardiokymographic and Electrocardiographic Stress Testing

“…Indications for termination were determined according to the guidelines of the American College of Cardiology/American Heart Association [18]. The exercise ECG was classified as abnormal if new horizontal or down-sloping ST-segment depressions of ≥0.1 mV (60 ms after the J point) were seen in three consecutive beats without baseline variation [18, 19]. If ST-segment depression was present at rest, an increase in the depression by ≥0.1 mV was classified as pathologic [18, 19].…”

“…The exercise ECG was classified as abnormal if new horizontal or down-sloping ST-segment depressions of ≥0.1 mV (60 ms after the J point) were seen in three consecutive beats without baseline variation [18, 19]. If ST-segment depression was present at rest, an increase in the depression by ≥0.1 mV was classified as pathologic [18, 19]. ST-segment elevations ≥0.2 mV were regarded as pathologic except for elevations in leads with signs of previous infarctions [19].…”
