How to Reduce the Risk of Heart Disease?

How to Reduce the Risk of Heart Disease? — A Practical Guide to Safeguarding Heart Health

As we learned earlier, the occurrence of heart disease is a “superimposed effect” of innate risks and acquired habits, and 80% of heart diseases can be prevented through scientific interventions. Targeting the core modifiable triggers, we can build a “protective shield” for heart health from aspects such as diet, exercise, lifestyle, and disease management. Below are medically validated practical suggestions that benefit both high-risk groups and the general population.

I. Dietary Adjustments: Lighten the Burden on Blood Vessels, Eating Right is Key

Diet is the “first line of defense” for regulating cardiovascular health, with the core principle of low salt, low fat, low sugar, and high fiber—replacing single restrictions with balanced nutrition.

1. Control Salt Intake: No More Than 5 Grams Per Day, Avoid “Hidden Salt”

A high-salt diet is a major cause of hypertension. It is recommended to limit daily salt intake to no more than 5 grams (about the amount of one beer cap). In addition to reducing salt in cooking, be extra vigilant about “hidden salt” in processed foods—such as pickles, ham, instant noodles, soy sauce, and snacks. When purchasing, check the ingredient list and choose “low-salt” or “salt-free” versions. Meanwhile, replace salt with natural seasonings like vinegar, lemon juice, and herbs to reduce sodium intake while enhancing flavor.

2. Choose Healthy Fats: Reject “Harmful Fats”

Not all fats are harmful; the key is to “avoid the bad and keep the good.” ① Reduce intake of saturated fats and trans fats: Avoid fried foods, fatty meats, animal offal, cream cakes, margarine, etc. These fats raise “bad cholesterol” (low-density lipoprotein) and accelerate atherosclerosis. ② Increase intake of unsaturated fats: Eat deep-sea fish (such as salmon and cod) 2-3 times a week to supplement Omega-3 fatty acids, which help lower blood lipids. Replace animal oils with vegetable oils like olive oil and rapeseed oil, limiting cooking oil to no more than 25 grams per day. Consume an appropriate amount of nuts (such as walnuts and almonds) and avocados to obtain healthy fats.

3. Limit Sugar: Stay Away from “Added Sugars” and Control Refined Carbohydrates

Excessive sugar intake can cause obesity and insulin resistance, indirectly increasing the heart’s burden. It is advisable to drink fewer sugary beverages (cola, milk tea, fruit juice), eat fewer desserts, candies, and refined carbohydrates (white rice, white bread, noodles). Replace part of the staple food with whole grains (oats, brown rice, quinoa) and mixed beans. This not only increases satiety but also slows blood sugar rise through dietary fiber, reducing the risk of dyslipidemia.

4. High Fiber + More Fruits and Vegetables: Act as “Scavengers” for Blood Vessels

Ensure daily intake of over 500 grams of vegetables (more than half being dark-colored vegetables like spinach, broccoli, and purple cabbage) and 200-350 grams of fruits (prioritize low-GI fruits such as apples, blueberries, and grapefruits). They are rich in vitamins, minerals, and dietary fiber, which can reduce blood viscosity and prevent plaque formation. In addition, consume an appropriate amount of soy products (tofu, soybean milk) and high-quality protein (chicken breast, eggs, lean meat) to provide nutritional support for the myocardium.

II. Regular Exercise: Get the Heart “Moving” and Avoid Sedentary Behavior

Exercise improves cardiovascular function, lowers blood pressure and blood lipids, and controls weight—it is a “natural remedy” for preventing heart disease. The key lies in “regularity” rather than “high intensity.”

1. Exercise Types: Aerobic Exercise as the Mainstay, Strength Training as a Supplement

• Aerobic exercise: Engage in at least 150 minutes of moderate-intensity aerobic exercise (such as brisk walking, jogging, swimming, cycling, square dancing) per week, or 75 minutes of high-intensity aerobic exercise (such as rope skipping, interval running), with each session lasting more than 30 minutes. The standard for moderate intensity is: being able to speak but not sing during exercise, and the heart rate reaching (170 – age) beats per minute (e.g., a 50-year-old person should keep their heart rate around 120 beats per minute).
• Strength training: Perform 2-3 sessions per week targeting limbs and core muscles (such as weightlifting, push-ups, squats, yoga), each lasting 20-30 minutes. Increased muscle mass boosts basal metabolism, helping control weight and blood sugar, and indirectly protecting the heart.

2. Precautions: Progress Gradually to Avoid Injury

• Sedentary people (sitting for more than 8 hours a day): Stand up and move for 5 minutes every 30 minutes, doing stretches, tiptoeing, chest expansions, etc., to avoid stagnant blood circulation.
• High-risk groups (such as patients with the “three highs” and the elderly): Consult a doctor before exercising, choose gentle exercise methods (such as tai chi, walking), and avoid strenuous exercise that may induce discomfort.
• Do not stop abruptly after exercise: Gradually reduce intensity, such as walking slowly for 5 minutes after running, to avoid dizziness or sudden increase in heart burden caused by sudden cessation.

III. Lifestyle Habits: Quit “Heart-Harming” Behaviors and Relieve the Heart’s Burden

Unhealthy lifestyle habits are “invisible promoters” of heart disease; correcting them in a timely manner can significantly reduce risks.

1. Quit Smoking and Limit Alcohol: The Most Direct “Heart-Protecting Actions”

• Quit smoking: Regardless of the length of smoking history, the risk of heart disease will gradually decrease after quitting—after 1 year of quitting, the risk of coronary heart disease is reduced by 50%; after 10 years, the risk is close to that of non-smokers. If it is difficult to quit directly, use nicotine replacement therapy (such as nicotine patches, gum) and stay away from secondhand and thirdhand smoke environments.
• Limit alcohol: It is best not to drink alcohol. If drinking is unavoidable, strictly control the amount—males should not exceed 25 grams of alcohol per day (about 750 milliliters of beer or 250 milliliters of red wine), and females should not exceed 15 grams (about 450 milliliters of beer or 150 milliliters of red wine). Avoid binge drinking.

2. Manage Stress: Prevent Emotions from “Harming the Heart”

Long-term anxiety and irritability can raise blood pressure and heart rate, damaging the vascular endothelium. It is recommended to regulate emotions through the following methods: ① Cultivate hobbies (such as gardening, listening to music, painting) to divert attention; ② Learn to talk and release stress by communicating with family and friends; ③ Spend 10-15 minutes a day meditating and taking deep breaths to relax; ④ Ensure adequate sleep, getting 7-8 hours of sleep per day and avoiding staying up late (staying up late disrupts the heart rhythm and increases the risk of arrhythmia).

3. Control Weight: Reduce the “Extra Burden” on the Heart

Obesity (BMI ≥ 28) or abdominal obesity (waist circumference ≥ 90 cm for males, ≥ 85 cm for females) directly increases the heart’s pumping burden and is accompanied by the “three highs.” It is recommended to lose weight scientifically through “diet + exercise,” aiming to keep BMI between 18.5-23.9 and waist circumference within the above standards. The weight loss rate should not be too fast—0.5-1 kilogram per week is appropriate to avoid myocardial damage caused by excessive dieting.

IV. Disease Management: Proactive Monitoring, Early Intervention for Peace of Mind

For people with underlying diseases such as the “three highs” and diabetes, as well as high-risk groups with a family history, “proactive management” is more important than “passive treatment.”

1. Regular Physical Examinations: Seize the Opportunity for “Early Detection”

• General population: Under 40 years old, undergo heart-related examinations (including blood pressure, blood lipids, blood glucose, electrocardiogram) every 2 years; over 40 years old or high-risk groups (with family history, obesity, “three highs”), undergo annual examinations. If necessary, add echocardiography and carotid ultrasound (to screen for atherosclerosis).
• Patients with the “three highs”: Monitor blood pressure and blood glucose monthly, and recheck blood lipids every 3-6 months. Adjust medication according to indicators (do not stop or reduce medication without authorization). The targets are: blood pressure 0/80 mmHg, fasting blood glucose .0 mmol/L, triglycerides mmol/L, and “bad cholesterol” 6 mmol/L (for high-risk groups).

2. Actively Treat Underlying Diseases: Prevent “Complications”

In addition to the “three highs,” diseases such as hyperthyroidism, chronic kidney disease, and rheumatic fever may also damage the heart. They need to be treated in a timely manner and reviewed regularly to control disease progression. For example, diabetic patients should strictly control blood glucose to avoid vascular and nerve damage; patients with chronic kidney disease need to monitor renal function to prevent water and sodium retention that raises blood pressure.

V. Special Populations: Targeted Protection to Precisely Reduce Risks

1. Elderly people (over 60 years old): Prioritize gentle exercises (such as walking, tai chi) and avoid strenuous bending and holding breath; follow a light and easy-to-digest diet, consume more high-quality protein (such as steamed egg custard, fish) to prevent malnutrition; keep warm in winter to avoid blood vessel constriction caused by cold stimulation.
2. Women (especially postmenopausal): Eat more calcium and estrogen-rich foods (such as soy products, milk) and supplement vitamin D to prevent osteoporosis while protecting blood vessels; monitor blood pressure and blood lipids regularly to avoid increased risks due to decreased estrogen levels.
3. People with a family history: Start prevention 10 years earlier than the general population (such as regular physical examinations from the age of 30), strictly control lifestyle habits, and avoid superimposed risks.

Summary: Protecting the Heart is a “Long-Term Project” — Start with Small Things

Reducing the risk of heart disease does not happen overnight; it is a “long-term action” integrated into daily life—quitting one cigarette, taking one more step, or eating one less bite of salt are all protections for the heart. Remember, the health of your heart depends on your daily choices. Even if you already have some risk factors, timely adjusting your lifestyle and actively managing diseases can still effectively delay or even avoid the occurrence of heart disease.

Starting today, try to start with small things like eating a light diet, exercising regularly, quitting smoking and limiting alcohol, so that the heart “engine” can operate smoothly and continuously, safeguarding your health.
