**7.4 Calcium channel blockers for acute coronary syndrome**

Calcium channel blockers have been effective in reducing ischemia in patients with NSTE-ACS and persistent ischemia despite treatment with full-dose nitrates and beta-blockers as well as in patients with contraindications to beta-blockers and among those with hypertension. Such patients should receive non-dihydropyridine calcium channel-blocking agents that lower the heart rate [9, 10].
