Some people with atrial fibrillation notice a racing or irregular heartbeat. Others experience fatigue, shortness of breath, or dizziness. However, many people have no obvious symptoms.
A healthcare professional may detect the condition through a pulse examination, electrocardiogram, or longer-term heart rhythm monitoring.
This is particularly important for older adults and people with heart disease, high blood pressure, or a previous stroke or TIA.
If atrial fibrillation is diagnosed, treatment may include medication to control the heart rhythm or rate and, for many patients, anticoagulant medication to reduce the risk of blood clots.
These medicines can be highly important, but they also carry bleeding risks. They must be prescribed and monitored according to the individual's medical situation.
Do not start aspirin or an anticoagulant on your own to prevent stroke.
A proper heart assessment can identify problems that might otherwise remain unnoticed.
3. Eat a Heart-Healthy Diet Rich in Vegetables and Fiber
Your everyday food choices can influence blood pressure, cholesterol, blood sugar, and body weight.
A dietary pattern that supports cardiovascular health usually includes plenty of vegetables, fruit, whole grains, beans, lentils, nuts, seeds, and appropriate sources of protein.
Fish, particularly oily fish, can provide omega-3 fatty acids. Olive oil and other unsaturated fats can be useful alternatives to large amounts of butter or foods rich in saturated fat.
The Mediterranean-style eating pattern is one example of a diet associated with better cardiovascular health.
A practical meal might include grilled fish, leafy vegetables, beans, tomatoes, whole grains, and a modest amount of olive oil.
Another option is oatmeal with fruit and unsalted nuts for breakfast, followed by a lunch containing vegetables and lean protein.
Fiber deserves special attention. Foods such as oats, beans, lentils, fruit, and vegetables can help improve cholesterol levels and support blood sugar control.
Try to reduce the frequency of meals dominated by processed meats, deep-fried foods, refined carbohydrates, and highly processed snacks.
You do not need to change everything overnight. Replacing one less nutritious food with a healthier alternative is a realistic place to begin.
For example, choose fresh fruit instead of a sugary dessert on some days, or prepare beans and vegetables more often instead of relying on processed meat.
A sustainable pattern matters more than following a restrictive diet for a few weeks.
4. Reduce Excess Salt to Support Healthy Blood Pressure
Salt contains sodium, and consuming too much sodium can contribute to elevated blood pressure in many people.
The problem is not limited to the salt shaker.
Large amounts of sodium can be hidden in packaged foods, instant noodles, processed meats, canned soups, salty sauces, seasoning powders, and restaurant meals.
People who eat these foods frequently may consume much more sodium than they realize.
One practical strategy is to prepare more meals at home using fresh ingredients.
You can add flavor with garlic, ginger, lemon, herbs, pepper, and other seasonings rather than relying heavily on salt.
When buying packaged foods, compare nutrition labels and choose products with less sodium.
The World Health Organization recommends that adults consume less than 2,000 milligrams of sodium per day, equivalent to less than 5 grams of salt. Individual needs may differ, and people with certain medical conditions should follow personalized medical advice.
There is no need to eliminate all salt from the diet. Sodium is an essential mineral. The goal is to avoid excessive intake.
People with kidney disease or those taking medications that affect potassium and fluid balance should be especially careful about using salt substitutes. Some contain potassium chloride, which may be unsafe for certain individuals.
Reducing excessive sodium is one of the simplest ways to support blood pressure control, particularly when combined with regular monitoring and prescribed treatment.
5. Stay Physically Active Throughout the Week
Regular physical activity helps improve several factors linked to stroke risk.
It can support healthy blood pressure, improve insulin sensitivity, help manage body weight, and contribute to better cardiovascular fitness.
You do not need to run long distances or perform intense workouts to gain benefits.
Walking is an accessible starting point for many adults. A brisk walk around the neighborhood, a short walk after meals, or several brief activity sessions throughout the day can all contribute to a more active routine.
For adults who are able, many health guidelines recommend at least 150 minutes of moderate-intensity aerobic activity each week, such as brisk walking, cycling, or swimming.
Muscle-strengthening activities on two or more days per week can also be beneficial.
Older adults should consider activities that support balance and mobility, such as appropriate strength exercises, gentle tai chi, or supervised movement classes.
The right routine depends on a person's current fitness and medical condition.
Someone with heart disease, severe arthritis, balance problems, or a recent stroke should discuss safe activity levels with a healthcare professional before starting a new exercise program.
Start gradually. A person who has been inactive for years does not need to begin with a demanding routine.
Consistency is more important than intensity.
6. Stop Smoking and Avoid Secondhand Smoke
Smoking damages blood vessels and increases the risk of cardiovascular disease.
Chemicals in tobacco smoke can injure the lining of arteries, contribute to plaque buildup, increase blood clotting tendencies, and reduce the amount of oxygen carried in the blood.
These effects can increase the likelihood of a stroke.
The risk is not limited to people who smoke heavily. Even regular exposure to tobacco smoke can harm cardiovascular health.
Quitting smoking is one of the most valuable steps a smoker can take to reduce future health risks.
Some people succeed by setting a quit date and changing their daily routines. Others benefit from counseling, support groups, nicotine replacement therapy, or prescription treatments.
A healthcare professional can help identify an approach that is appropriate for the person's health and smoking history.
It may take several attempts to quit successfully. A relapse does not mean that further efforts are pointless.
Family members can help by creating a smoke-free home and avoiding smoking around older relatives or people with heart and lung conditions.
The goal is not only to stop active smoking but also to reduce exposure to secondhand smoke.
7. Manage Diabetes and Keep Blood Sugar Within Your Target Range
Diabetes can damage blood vessels over time and increase the risk of stroke.
Persistently elevated blood sugar can contribute to changes in blood vessels, while diabetes often occurs alongside other cardiovascular risk factors such as high blood pressure, abnormal cholesterol, and excess body weight.
People with diabetes should work with their healthcare team to establish an appropriate management plan.
This may involve regular blood glucose monitoring, HbA1c testing, medication, dietary adjustments, and physical activity.
The correct blood sugar target is not the same for everyone. Older adults with multiple medical conditions may need a different approach from younger people with fewer health problems.
Trying to achieve very low blood sugar at all costs can be dangerous, especially for people taking insulin or certain medications that can cause hypoglycemia.
Symptoms of low blood sugar may include sweating, shaking, hunger, dizziness, and confusion. Severe hypoglycemia can become an emergency.
The goal is safe and consistent diabetes management, not extreme restriction.
If you have been diagnosed with diabetes, regular follow-up appointments are important even when you feel well.
8. Maintain a Healthy Weight and Limit Alcohol
Excess body weight, particularly when associated with high blood pressure, diabetes, and abnormal cholesterol, can increase cardiovascular risk.
