A case-control study of patients on antihypertensive drugs related an increased risk of myocardial infarction (MI) for patients using calcium channel blockers. In this study, cases were antihypertensive drug patients who had suffered a first fatal or nonfatal MI through 1993, and controls were antihypertensive drug patients, matched by demographic factors, who had suffered a MI. Among the comparisons reported were patients receiving calcium channel (CC) blockers (with and without diuretics) and patients receiving ß-blockers (with and without diuretics). Results of numbers of patient by drug/MI status combination are given in the following table. Antihypertensive OHO: p1p2 vs. Ha: p1 < p2 O HO: p1> p2 vs. Ha: p1=p2 Drug Does it appear that an increased risk of myocardial infarction (MI) is related to using calcium channel (CC) blockers? The case-control nature of this study requires we compare the proportion of CC blocker users among those had MI attack (p1) vs. the proportion of CC blocker users among those had no MI (p2).

True or False? We have strong evidence against H0: p1 = p2 and support the claim that an increased risk of myocardial infarction (MI) is related to using calcium channel (CC) blockers.

 

A case-control study of patients on antihypertensive drugs related an increased risk of myocardial infarction (MI) for patients using calcium channel blockers. In this study, cases were
antihypertensive drug patients who had suffered a first fatal or nonfatal MI through 1993, and controls were antihypertensive drug patients, matched by demographic factors, who had not
suffered a MI. Among the comparisons reported were patients receiving calcium channel (CC) blockers (with and without diuretics) and patients receiving B-blockers (with and without
diuretics). Results of numbers of patient by drug/MI status combination are given in the following table.

Does it appear that an increased risk of myocardial infarction (MI) is related to using calcium channel (CC) blockers? The case-control nature of this study requires we compare the
proportion of CC blocker users among those had MI attack (p1) vs. the proportion of CC blocker users among those had no MI (p2).
