Unlike heart attacks (myocardial infarction), which are typically caused by clogged coronary arteries reducing blood flow to the heart muscle, sudden cardiac arrest is the result of defective electrical impulses. (sciencedaily.com)
Compared to men, women can have less severe blockages that do not require any stents; yet the heart's coronary artery blood vessels are damaged which results in decreased blood flow to the heart muscle. (sciencedaily.com)
Further evidence exists to explain how the coenzyme improves blood flow to the heart muscle and enhances vascular elasticity to prevent arterial stiffening, commonly referred to as «hardening of the arteries». (liveinthenow.com)
