Group of answer choices Most accurate measurement of exercise capacity useful in defining prognosis and defining the timing of cardiac transplantation and other advanced therapies in patients with heart failure helpful in the differential diagnosis of patients with suspected cardiovascular and respiratory diseases A high exercise capacity is indicative of a high cardiac output and therefore suggests the absence of serious limitations of left ventricular function All of the above A, C, and D
- A study is run to evaluate the effectiveness of an exercise program in reducing systolic blood pressure in patients with pre-hypertension (defined as a systolic blood pressure between 120-139 mmHg or a diastolic blood pressure between 80-89 mmHg). A total of 15 patients with pre-hypertension enroll in the study, and their systolic blood pressures are measured. Each patient then participates in an exercise training program where they learn proper techniques and execution of a series of exercises. Patients are instructed to do the exercise program 3 times per week for 6 weeks. After 6 weeks, systolic blood pressures are again measured. QUESTIONS: What type of nonparametric test should be used to evaluate the effectiveness of an exercise program in reducing systolic blood pressure?
