Abnormal recovery systolic blood pressure response for detecting coronary artery disease in men and women investigated by upright bicycle exercise.

We investigated the clinical significance of recovery systolic blood pressure (SBP) ratio, obtained dividing the recovery SBP at 1st (R1/A) or 3rd min (R3/A) by the peak exercise SBP (before stopping), during upright bicycle exercise in 530 subjects (ranging from 17 to 73 years). Our results may be summarized as follows: 1) we found a higher value of R1/A in control subjects with exercise induced ST depression; 2) the normal range in women was higher than in men; 3) the use of recovery SBP ratios gives a lower sensitivity and a higher specificity than ST segment analysis in detection of CAD; 4) this pattern may be useful particularly in patients with previous myocardial infarction and not detectable ST segment analysis during exercise.

Exercise time: a possible source of misleading results during long-term pharmacological studies by multiple stress testings in coronary artery disease.

The assessment of chronic pharmacological treatment of stable angina requires serial exercise stress testings. It is well known that exercise tolerance can be improved by the training effect of performing repeated testings. Our study investigated the values of heart rate, systolic blood pressure, rate-pressure product, and duration of exercise at 0.

Atenolol and/or nifedipine in effort angina: which is the treatment of choice for exercise coronary protection?

The authors performed a long-term, double-blind, crossover, randomized study on the effects of two drugs (atenolol, 100 mg/day, or nifedipine, 10 mg t.i.d.

Long-term management of exercise-induced myocardial ischemia. Diltiazem versus propranolol, a double-blind, crossover study.

The authors performed a long-term, double-blind, crossover study on the effect of two drugs (propranolol, 40 mg t.i.d.
