Heart Disease Is More Than a Cholesterol Problem: Other Causes of Vascular Injury

If Many Heart Attack Patients Have Normal Cholesterol, What Else Is Driving Heart Disease?

Heart disease remains the leading cause of death in the United States and is a major contributor to disability and healthcare costs worldwide. Despite advances in treatment, cardiovascular disease risk factors continue to affect millions of Americans. Most people have heard that high cholesterol is a major cause of heart disease. While LDL cholesterol is an important risk factor, research continues to show that heart disease prevention requires a much broader approach.

Cholesterol Matters—But It Is Not the Entire Story

LDL cholesterol plays a role in plaque formation and cardiovascular disease progression. However, focusing solely on cholesterol may overlook other important drivers of vascular injury.

Understanding Endothelial Dysfunction and Vascular Injury

Your blood vessels are lined with a thin layer of cells called the endothelium. When this protective lining becomes damaged, endothelial dysfunction can occur, leading to increased vascular inflammation and cardiovascular risk.

Common Causes of Vascular Injury

High blood pressure, insulin resistance, chronic inflammation, smoking, oxidative stress, elevated homocysteine, gut microbiome imbalances, environmental toxins, hormonal imbalances, and physical inactivity all contribute to cardiovascular disease risk.

Nutrition Strategies for Heart Disease Prevention

The Mediterranean diet, DASH diet, and regular use of extra virgin olive oil are among the most evidence-based nutritional approaches for supporting cardiovascular health.

Lifestyle Habits That Support Cardiovascular Health

Move more, prioritize sleep, manage stress, and support oral health to improve vascular function and reduce cardiovascular risk.

Concerned About Your Cardiovascular Risk?

Many people focus solely on cholesterol numbers, yet cardiovascular health is influenced by inflammation, blood sugar regulation, blood pressure, nutrition, gut health, sleep, stress, and lifestyle habits. At Food Centered Solutions, I help individuals identify and address the underlying factors that may contribute to cardiometabolic and cardiovascular risk. If you'd like a personalized review of your diet, lifestyle habits, laboratory values, and cardiovascular risk factors, schedule a complimentary 15-minute discovery call.
