Cholesterol Normal? Heart Attack Risk Still Exists
24 Sep
Summary
- Normal cholesterol doesn't guarantee a healthy heart.
- Lipoprotein(a), inflammation, and metabolic health are key.
- Lifestyle factors like stress and pollution increase risk.
A heart attack can occur even when cholesterol levels appear normal, challenging a common misconception about heart health. While LDL cholesterol is a known contributor to plaque buildup, its absence in standard tests leaves other critical risk factors unexamined.
Experts point to inherited factors like Lipoprotein(a) (Lp(a)) as significant contributors to heart disease. Unlike LDL, Lp(a) levels are genetically determined and not easily influenced by diet or exercise. Inflammation, measured by markers like CRP, is another key factor that can weaken plaques and increase heart attack risk, regardless of cholesterol readings.
Metabolic health issues, including insulin resistance and metabolic syndrome, can silently damage blood vessels over time. Furthermore, a sedentary lifestyle, chronic stress, poor sleep, smoking, and even air pollution all place undue strain on the cardiovascular system, independently raising the risk of heart problems.
Individuals experiencing unexplained fatigue, high stress, or possessing risk factors like diabetes or obesity should consult a doctor for a detailed heart health evaluation. This assessment should encompass more than just routine cholesterol checks to address the multifaceted nature of heart disease.
