Calcium channel blockers and atherosclerosis

Abstract:
There is evidence that calcium antagonists (calcium channel blockers) may suppress atheroma formation in animals fed high-fat diets. Studies on the antiatherosclerotic effects of calcium blockers have suggested a variety of possible mechanisms: (a) lowering of arterial pressure, (b) decrease in atherogenic plasma lipoproteins, (c) suppression of accumulation of intracellular lipids, (d) suppression of atherogenic platelet dysfunction, (e) prevention of dyslipidemic endothelial injury, (f) inhibition of chemotaxis and cell migration, (g) inhibition of cell proliferation, (h) inhibition of deposition of matrix proteins, (i) suppression of tissue mineralization, and (j) retardation of cell necrosis. Although it is tempting to ascribe the antiatherosclerotic effects of calcium blockers to a blockade of calcium channels, other possible common mechanisms of action involving low-affinity drug-binding sites must be considered. Recently, two randomized, prospective clinical trials designed to determine the effects of calcium channel blockers on the progression of coronary artery disease have been completed. Results of the trials suggest that calcium channel blockers suppressed the progression of coronary atherosclerosis. The utility of calcium channel blockers for the treatment of atherosclerosis will require further evaluation.
Insights
Calcium channel blockers show promise in suppressing atherosclerosis progression. Clinical trials suggest these calcium antagonists may be beneficial in treating coronary artery disease, warranting further investigation.
Area of Science:
- Cardiovascular Research
- Pharmacology
- Atherosclerosis Research
Background:
- Calcium antagonists (calcium channel blockers) have demonstrated potential in animal models for suppressing atheroma formation.
- Multiple proposed mechanisms underlie the antiatherosclerotic effects of calcium blockers, including effects on arterial pressure, lipoproteins, and cellular processes.
- The precise mechanisms may involve both calcium channel blockade and other drug-binding interactions.
Purpose of the Study:
- To evaluate the effects of calcium channel blockers on the progression of coronary artery disease.
- To synthesize evidence regarding the antiatherosclerotic properties of calcium antagonists.
Main Methods:
- Review of existing animal studies on calcium blockers and atheroma formation.
- Analysis of results from two recent randomized, prospective clinical trials focused on coronary artery disease progression.
Main Results:
- Evidence suggests calcium channel blockers can suppress atheroma formation in animal models.
- Clinical trial results indicate that calcium channel blockers suppressed the progression of coronary atherosclerosis.
Conclusions:
- Calcium channel blockers demonstrate potential in mitigating atherosclerosis progression.
- Further clinical evaluation is necessary to establish the therapeutic utility of calcium channel blockers for treating atherosclerosis.

Antiepileptic Drugs: Calcium Channel Blockers
Calcium channel blockers exert their antiepileptic effects by targeting T-type calcium channels, which are integral to transmitting nerve signals in the central nervous system. These channels allow the passage of calcium ions, which are vital for neuronal communication. By inhibiting T-type calcium channels, calcium channel blockers effectively reduce the release of neurotransmitters and...
