In continuation of our last blog on what is an enlarged heart, today we would discuss ” how to diagnose an enlarged heart and treatment options for the same”
Early diagnosis is critical to managing an Enlarged Heart.
Upon a physical examination, a cardiologist may hear a murmur in the heart, unusual heartbeats, water retention in the legs, abdomen, fluid retention in the lungs.
After a physical examination, a few tests that may be carried out are :
Angiogram or catheterization, checks for blockages in the heart. A flexible tube is inserted via the groin, dye injected and pictures of the heart taken to check for blockages and heart function. In case of blockages, stenting or angioplasty is carried out at the same time.
ECG uses electrodes to detect heart activity.
Echo, uses sound waves to detect heart activity and take pictures of the heart.
MRI is used to take pictures of the heart and blood vessels to detect anomalies.
CT Scan is also used to take pictures of the arteries in the heart and is often used for patients with pacemakers and other implanted devices.
Stress Echo: The patient is made to exercise and then heart tests are administered. Along with ECG, Stress Echo shows heart rate, rhythm, and activity.
Some of the common treatment options are:
Angioplasty or Stenting are often carried out when blockages or fat, calcium deposits are found in the arteries.Stents can be bare metal or drug-eluting which help open up the arteries.
Heart Valve surgeries, such as single valve repair, DVR( Double valve replacement ), MVR(Mitral valve replacement, Mital valve repair), VSD, ASD help take care of valve-related heart problems which impair blood flow and lead to an enlarged heart over time.
VAD or Ventricular assist devices, help in heart failure by helping a weak heart pump blood. VAD can be, LVAD( left ventricular assist device) or RVAD( Right ventricular assist device). ICD combo devices and Pacemakers also help weak hearts or a heart with impaired function.
We often hear of an enlarged heart, what does it mean? How does one’s heart get enlarged? And how does it affect our health?
Our heart is a pear-shaped muscle pumping oxygen-rich blood throughout the body.
Sometimes due to certain factors, birth defects- congenital heart defects, our heart muscle has to work much harder causing it to enlarge or become bigger in size.
Once the heart becomes enlarged, it is almost impossible to get it back to the original size.Therefore timely detection and management is the key.
Let’s try and explore factors which lead to an enlarged heart, a medical condition, which is impossible to cure but can be managed medically.
Congenital heart defects or heart defects one is born with us as PDA, VSD, ASD, Mitral valve defect, left untreated lead to high pulmonary pressures, which in turn lead to thickening of the arterial wall and also an enlarged heart.Though most babies are routinely scanned for congenital heart defects in developed countries, treatment upon detection and early intervention and management still remains the key.Many parents despite detection, are often scared to get surgical interventions without realizing that they are hampering both mental and physical growth and putting children at risk of enlarged heart and other complications later on in life.
Lifestyle-related complications such as hypertension or high blood pressure also lead to an enlarged heart over a period of time.In case of high blood pressure, the heart has to pump harder to deliver blood to the rest of your body, thereby thickening and enlarging the heart muscle.High blood pressure may also enlarge the upper chambers of the heart, the left ventricle and also weaken the heart long-term.
Coronary artery disease or CAD (blocked arteries requiring stenting, angioplasty) can also lead to a heart attack. A part of the heart muscle dies during a heart attack, causing the heart muscle to work harder to supply blood to the entire body which over long-term leads to an enlarged heart.
Abnormal Heart Beat or Arrhythmia is often ignored but may cause an enlarged heart over a period of time.
Anemia or low level of iron in the body, where the body doesn’t have enough Red Blood Cells to carry blood to the body, leads to rapid, irregular heartbeat causing the heart to pump harder to make up for lack of sufficient oxygen in the blood.Sicklers or patients suffering from sickle cell anemia are at an increased risk and despite hearsay, a Bone Marrow Transplant or a BMT remains the only curative treatment for Sickle Cell Anemia, Thalassemia Major.
Thyroid disorders, also lead to various heart diseases over a period of time leading to an enlarged heart.
The biggest complications arising from an enlarged heart are heart failure, SCA or SCD (sudden cardiac arrest or sudden cardiac death) or what is known as a silent heart attack in laymen language.
Heart Failure: During heart failure, the heart muscle weakens and the ventricles, stretch or dilate to a point that the heart cannot pump blood efficiently, leading to a sudden cardiac arrest.
Silent heart attack or SCD: An enlarged heart causes the heart rhythm to be so slow that the muscle is unable to move blood or it may cause a heart rhythm, so fast that the muscle is unable to beat properly resulting in sudden death.
More on diagnosis and treatment options in our next post.
Uncontrolled blood pressure can damage the heart , the main organ responsible for pumping blood in the body in a number of ways.
Cause narrowing of arteries- As the pressure of blood flowing from your arteries increases. it damages the inner lining of your arteries. Fat from food collects in the damaged part of your arteries causing further narrowing and damage. Eventually arteries become less elastic limiting proper blood supply to the body.
Coronary heart disease- As the arteries get damaged due to narrowing, a high blood pressure can lead to sudden chest pains and subsequent heart attack or even arrhythmias.
Enlarged Left Heart– As high blood pressure forces the heart to work harder to pump blood , the left ventricle or the left heart becomes thicker and tougher increasing risk of heart attack, heart failure or a cardiac arrest.
Heart Failure- Over a period of time, the heart becomes, weaker, less efficient and begins to fail.
