Cardiology is the medical specialty focused on the heart and the cardiovascular system. It involves the diagnosis, treatment, and prevention of conditions affecting the heart and blood vessels. These conditions include coronary artery disease, heart failure, arrhythmias (irregular heartbeats), and valve disorders. The field covers a broad spectrum, from congenital heart defects present at birth to acquired conditions like heart attacks.

Living with structural heart disease, or recovering from a procedure to fix it, is a long-term commitment to your health. The repair of a valve or the closure of a hole is a new beginning, not the end of the journey. To get the most out of your treatment and to protect the rest of your cardiovascular system, lifestyle choices matter immensely. You can’t change your past or genetics, but you can shape your future with daily choices.
This final section focuses on the practical steps you can take to maintain a healthy heart. We will look at nutrition that fuels the heart muscle, the right way to approach physical activity, and the often-overlooked connection between dental health and heart valves. We will also discuss the mental aspect of living with a chronic condition and the importance of staying connected with your medical team. These are the tools that empower you to live a full, active, and vibrant life.
Food is medicine for the heart. A diet rich in nutrients helps manage blood pressure, cholesterol, and body weight—all of which reduce the strain on your heart valves and chambers. The goal is not to follow a restrictive “diet” for a few weeks but to adopt a way of eating that you can sustain for life.
The Mediterranean-style diet is widely considered the best approach for heart health. It emphasizes plant-based foods like fruits, vegetables, whole grains, beans, and nuts. It uses olive oil instead of butter and includes moderate amounts of fish and poultry. Red meat and processed sweets are eaten sparingly. This way of eating reduces inflammation in the body and keeps blood vessels flexible.
For patients with structural heart disease, especially those with a history of heart failure, salt (sodium) is a critical factor. Salt acts like a sponge; it holds onto water in your body. Excess water increases the volume of blood the heart has to pump, which raises blood pressure and can cause fluid to back up into the lungs or legs.
Aiming for less than 2,000 mg of sodium a day is a standard recommendation. This involves reading labels, as most salt comes from processed foods like canned soups, deli meats, and bread, not just the salt shaker. If your doctor recommends it, it’s crucial to manage your fluid intake to avoid overstressing your heart.
Alcohol can be toxic to heart muscle cells if consumed in excess and can trigger arrhythmias like atrial fibrillation. If you have structural heart issues, moderation is key. Caffeine is generally safe for most people, but if you are sensitive to it, it might trigger palpitations. Listen to your body; if coffee makes your heart race, switch to decaf.
Exercise is essential for strengthening the heart muscle and improving circulation. However, with structural heart disease, the type and intensity of exercise matter. The goal is to be active enough to gain benefits without putting dangerous strain on a compromised valve.
Aerobic exercise, such as walking, swimming, or cycling, is generally excellent. It trains the heart to be more efficient. Start slow and build up gradually. If you have had a procedure, cardiac rehabilitation is the best place to start. If you have untreated severe aortic stenosis, you must be cautious with exertion and should strictly follow your doctor’s limits, as heavy exercise can be risky before the valve is fixed.
While light weights are beneficial for toning, heavy weightlifting (isometric exercise) can cause a sudden, massive spike in blood pressure. This puts immense pressure on the valves and aortic wall. Avoid straining, grunting, or holding your breath while lifting. Focus on more repetitions with lighter weights rather than lifting the heaviest weight possible.
One of the most surprising but critical links in heart health is the connection between your mouth and your heart. Your mouth is full of bacteria. If you have gum disease or an abscess, these bacteria can enter your bloodstream while you chew or brush your teeth.
These bacteria have the ability to enter the bloodstream, travel to the heart, and adhere to artificial valve replacements or damaged valves. This causes a serious infection called infective endocarditis, which can destroy a valve. Therefore, excellent dental hygiene is non-negotiable. Brush and floss daily, and see your dentist regularly. If you have an artificial valve or certain congenital defects, you will need to take a dose of antibiotics one hour before any dental work (like a cleaning or extraction) to protect your heart.
Deep connections exist between the mind and the heart. A diagnosis of heart disease can lead to anxiety, depression, or fear of movement. This emotional stress releases hormones like cortisol and adrenaline, which raise blood pressure and heart rate. Chronic stress keeps the heart in overdrive.
Finding ways to manage stress is a medical necessity. This could be through deep breathing exercises, meditation, spending time in nature, or connecting with loved ones. Prioritize sleep, as sleep apnea (a condition where you stop breathing at night) puts severe strain on the right side of the heart. If you snore loudly or wake up worn out, get tested for sleep apnea.
Structural heart disease is often a lifelong condition. Even after a valve is repaired or replaced, you need regular checkups. Artificial valves need to be monitored to ensure they are working well. Native valves need to be watched to see if disease is progressing in other areas.
You will typically have an echocardiogram every year or two. Keeping these appointments is vital. It allows the doctor to catch changes early, often before you feel symptoms. It is also a chance to adjust medications and discuss any new sensations you are feeling.
You do not have to face this alone. There are many patient support groups for people with valve disease or congenital heart defects. Talking to others who have undergone a TAVR procedure or lived with a heart murmur can be incredibly reassuring. They can share practical tips for recovery and help normalize the experience.
Lean on your family and friends. Let them know what you need, whether it is a walking buddy, help with grocery shopping, or just someone to listen. Being open about your condition helps build a safety net around you.

Yes. With proper monitoring and treatment, most people with structural heart disease live full, active lives. Modern therapy aims to restore your quality of life so you can enjoy your hobbies.
If you have an artificial heart valve, a history of endocarditis, or certain congenital heart defects, yes. You should remind your dentist and doctor about your heart condition before any dental procedures.
It depends on the specific defect and its severity. Pregnancy puts a significant extra load on the heart. Women with structural heart issues should consult a specialist in “cardio-obstetrics” before becoming pregnant to understand the risks and plan for a safe delivery.
Diet cannot “unstiff” a calcified valve or seal a hole. However, a heart-healthy diet prevents plaque buildup in the arteries and controls blood pressure, which stops the disease from getting worse and protects the heart muscle.
If you gain 2–3 pounds a day or 5 pounds a week, call your doctor. This is often fluid retention (water weight), not fat, and it is an early warning sign that your heart is struggling to pump efficiently. You may need an adjustment in your diuretic medication.
