Heart Attack Triggers in Women

Heart Attack Triggers in Women: Following the COVID-19 pandemic, there has been a significant rise in heart attack incidents, affecting even younger individuals. Traditionally, it has been thought that the primary cause of heart attacks is the buildup of fat or elevated cholesterol levels in blood vessels. However, recent findings from the Mayo Clinic have unveiled surprising insights. The research indicates that numerous factors contribute to heart attacks in individuals under 65, particularly in women, who often receive less attention regarding this issue.

According to a report from the Mayo Clinic News Network, a recent study reveals that over 50% of heart attacks in women under 65 are not linked to arterial blockages. The leading causes include spontaneous coronary artery dissection (SCAD), embolism, infections, and anemia. SCAD occurs when the artery walls of the heart unexpectedly tear or rupture, disrupting blood flow and depriving the heart of oxygen, which can result in a heart attack. This condition frequently affects seemingly healthy women with minimal cardiovascular risk factors. The study analyzed data spanning 15 years.

The findings indicate that heart attacks in women are often misdiagnosed. For instance, SCAD may be incorrectly identified as a heart attack resulting from blocked arteries. Additionally, hormonal fluctuations, postpartum conditions, and genetic predispositions can elevate the risk of SCAD and other non-plaque-related causes. Embolism, which happens when a clot or foreign object obstructs blood vessels, along with conditions like infections and anemia, can also place additional strain on the heart. Heart attacks stemming from these causes have shown a higher mortality rate after five years.

Traditionally, medical understanding attributes heart attacks primarily to arterial blockages, known as atherosclerosis, resulting from cholesterol and plaque accumulation. However, this study highlights that these conventional causes do not always apply, especially in younger women. If healthcare providers focus solely on plaque, they may overlook SCAD or other underlying causes. The research advocates for a treatment approach tailored to the specific cause of heart attacks rather than relying solely on the assumption of arterial blockage. In cases of SCAD, conservative management might be more appropriate than immediate stent placement.
