[3] Calcium channel blockers are used as antihypertensive drugs, i.e., as medications to decrease blood pressure in patients with hypertension.

   Participants were initially randomised to chlorthalidone versus doxazosin (alpha-adrenergic blocker), lisinopril (ACE-inhibitor), and amlodipine (calcium channel blocker). [ 2 ] [ 3 ] The doxazosin arm was discontinued early on in the trial because of a higher rate of combined cardiovascular events and admissions for heart failure compared with ...

   Heart failure may be worsened with nondihydropyridine calcium channel blockers, the alpha blocker doxazosin, and the alpha-2 agonists moxonidine and clonidine. On the other hand, β-blockers, diuretics, ACEis, ARBs, and aldosterone receptor antagonists have been shown to improve outcome.

   Certain calcium channel blockers, such as diltiazem and verapamil, are known to decrease the force with which the heart ejects blood, thus are not recommended in people with heart failure with a reduced ejection fraction. [54] Breast cancer patients are at high risk of heart failure due to several factors. [55]

7. Hypertrophic cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Hypertrophic_cardiomyopathy

   For people who cannot tolerate beta blockers, nondihydropyridine calcium channel blockers such as verapamil can be used, but are potentially harmful in people who also have low blood pressure or severe shortness of breath at rest. These medications also decrease the heart rate, though their use in people with severe outflow obstruction ...
