Prevent heart attack and stroke with 4 simple, doctor-approved steps

Prevent heart attack and stroke: 4 doctor-approved steps backed by new study

A groundbreaking study published in the Journal of the American College of Cardiology has revealed a powerful but simple truth: more than 99% of people who experienced a heart attack, stroke, or heart failure had at least one preventable risk factor beforehand.

The study analyzed millions of medical records from both the United States and South Korea and identified four key cardiovascular risk factors that were consistently present before serious heart problems: high blood pressure, elevated cholesterol, high fasting glucose or diabetes, and current or past tobacco use. Among these, high blood pressure was the most common.

Why this matters

Cardiovascular disease remains the world’s leading cause of death. The new research highlights that prevention is not about miracle cures but about simple, everyday actions. According to Philip Greenland, MD, senior author of the study, “If the modifiable factors are actually present in almost all cases, then there is an opportunity for prevention.”

The 4 simple, doctor-approved steps

Adopting these science-backed habits can significantly reduce the risk of cardiovascular disease:

• Measure and manage blood pressure regularly: Get your blood pressure checked at least once a year. Lifestyle changes such as reducing salt, exercising, managing stress, and taking prescribed medicines when needed are proven to lower risk.
• Check and control cholesterol and blood sugar: Routine cholesterol and glucose tests help detect problems early. Whole-food eating patterns and treatment plans for high cholesterol or diabetes are effective at prevention.
• Quit tobacco and avoid secondhand smoke: Quitting smoking delivers immediate health benefits. Counseling and approved medications improve success rates.
• Move more, eat better, limit alcohol: Swap prolonged sitting for simple daily walks, choose unprocessed foods more often, and reduce excess alcohol intake. These shifts increase the likelihood of staying in the “ideal” range for multiple health markers.

Why blood pressure needs extra attention

The study found high blood pressure was the most common risk factor across both countries studied. “High blood pressure is fairly easily detectable but it is asymptomatic, so often overlooked,” says Dr. Greenland. Regular screening is a low-cost and highly effective prevention tool.

What the experts say

• Philip Greenland, MD: “If there is even a slight elevation as per our paper, efforts need to be made to treat that factor to prevent heart attack, stroke, or heart failure.”
• Cheng-Han Chen, MD, interventional cardiologist: “This study should further drive public health screening and prevention of cardiovascular disease risk factors.”

Who benefits most?

Everyone, young and old. The study found that even women under 60 often had at least one non-optimal factor before a cardiovascular event. Early detection and consistent lifestyle improvements can protect long-term heart health.

Quick action checklist

• Check your blood pressure today at a pharmacy or clinic.
• Schedule blood tests for cholesterol and fasting glucose.
• If you smoke, ask for a quit plan with professional support.
• Begin 20–30 minutes of walking or physical activity daily.
• Replace one ultra-processed meal with a whole-food option.

Final note: prevention is powerful

This study makes it clear: almost every serious heart problem can be traced back to a few key, modifiable risks. Prevention is not complicated or unrealistic — it is practical, science-backed, and accessible. Talk to your healthcare provider about your personal risk and how to start these four steps safely. Prevention is powerful, and the best time to begin is now.
