A heart attack happens when the supply of blood to the heart is suddenly blocked, usually by a good clot.
Lack of blood to the heart may seriously damage the heart muscle and can be life-threatening.
According to the NHS, symptoms of a heart attack can include chest pain, shortness of breath, feeling weak or lightheaded, and an overwhelming feeling of anxiety.
But to avoid one happening in first place, the American Heart Association suggests making four simple lifestyle changes.
Choose good nutrition
The food you eat can affect other controllable risk factors, cholesterol, blood pressure, diabetes and overweight.
The charity says: “Choose nutrient-rich foods. Choose a diet that emphasises intake of vegetables, fruits and whole grains, includes low-fat dairy products, poultry, fish, legumes, nontropical vegetable oils, and nuts, and limits intake of sweets, sugar-sweetened beverages, and red meats.
“And to maintain a healthy weight, coordinate your diet with your physical activity level so you are using up as many calories as you take in.”
Be physically active every day
Research has shown that three to four sessions per week, lasting on average 40 minutes per session, and involving moderate-to-vigorous-intensity physical activity can help lower blood pressure, lower cholesterol and keep your weight at a healthy level.
But the charity says, something is better than nothing. It says: “If you’re doing nothing now, start out slow. Even 10 minutes at a time may offer some health benefits.
“Studies show that people who have achieved been a moderate level of fitness are much less likely to die early than those with a low fitness level.”
A few studies have noted a relationship between coronary heart disease risk and stress in a person’s life that may affect the risk factors for heart disease and stroke.
American Heart Association gives and example: “People under stress may overeat, start smoking or smoke more than they otherwise would. Research has even shown that stress reaction in young adults predicts middle-age blood pressure risk.”
Drinking too much alcohol can raise blood pressure, increase cardiomyopathy, stroke, cancer, and other diseases. It can contribute to high triglycerides and produce irregular heartbeats. Excessive alcohol consumption contributes to obesity, alcoholism, suicide and accidents.
The charity adds: “There is a cardioprotective effect of moderate alcohol consumption. If you drink, limit your alcohol consumption to no more than two drinks per day for men and no more than one drink per day for women.”
But it is not recommended that nondrinkers start using alcohol or that drinkers increase the amount they drink.
If high blood pressure is left untreated it can lead to a heart attack. A new study gas found eating well-done meat can cause hypertension.
