Understanding the Link Between High Cholesterol and Heart Attacks
This article explains the connection between high cholesterol levels and increased heart attack risk. It highlights the importance of maintaining healthy cholesterol through diet, exercise, and medical interventions such as angioplasty. Understanding cholesterol types and levels can help prevent heart-related issues effectively.

The Connection Between Elevated Cholesterol and Heart Attack Risk
Cholesterol plays a vital role in the body by supporting cell formation, insulating nerves, and hormone synthesis. Our liver produces sufficient cholesterol, but it is also consumed through foods like dairy, eggs, red meats, and processed snacks high in trans fats and saturated fats. Excessive cholesterol levels heighten heart attack risk, making it crucial to keep cholesterol within healthy ranges.
Cholesterol exists in three forms: LDL (bad cholesterol), HDL (good cholesterol), and triglycerides stored as fats in the body. Elevated LDL and triglycerides combined with low HDL increase cardiovascular risks. Maintaining healthy cholesterol levels through diet and exercise is essential for heart health.
Normal cholesterol levels include HDL above 55 mg/dL for women and 45 mg/dL for men, LDL below 130 mg/dL (or 100 mg/dL for those with heart disease or diabetes), and triglycerides under 150 mg/dL. High LDL and triglycerides cause arterial plaque buildup, leading to atherosclerosis, narrowing arteries, and restricting blood flow to the heart.
High HDL levels help remove excess fats and protect heart health, achievable through physical activity and omega-3 intake. Blockages in coronary arteries hinder oxygen supply, potentially resulting in ischemic pain or a heart attack. Procedures like angioplasty and medications help restore normal cholesterol levels and artery function.
