What is heart disease? How is it treated?

 The heart is one of the most important parts of our body, which pumps continuously from the day you are born to your last breath. The heart is the organ which continuously pumps from the day of your birth. For pumping it requires more energy. So that nature has provided three main vessels we call as a coronary artery which supplies blood to the heart itself. The heart is the organ which supplies blood to the entire body. These coronary arteries are the main artery which supplies blood itself to the heart muscle. There are many diseases which affect your heart. In that, the most common and deadliest is what we call as the coronary artery diseases.

So what is coronary artery disease? It is the blockage which happens in the coronary artery, so that blood flow to the heart muscle is completely stopped or it is partially blocked. Wherever there is an obstruction which can happen in the coronary artery the blood to the proximal part or the distal part of the vessels is blocked. So there is a deficiency of the blood flow to the heart muscle. When there is a deficiency of blood flow to the heart muscle we call it as ischemia and the patient develops symptoms called chest pain or Angina.  Whenever the patient exerts himself, walking it causes a chest pain because of the deficiency of blood flow. This deficiency of the blood flow is identified by many investigation procedures. But once they identify that the patient has coronary artery blockage by simple non-invasive investigations like an ECG or treadmill, the physician put him on, what we call as medical management.

There are a lot of other options available for these patients, who have a blockage in the coronary artery and their medical management even though it is optimal or maximal still the patient complaints of chest pain and poor quality of life.  In that case, there are other treatments which are available for this kind of patient called as invasive and non-invasive treatment options. In the non-invasive option available to the patients, one of the important treatment options is called enhanced external counter pulsation. It is absolutely a non-invasive treatment.  Other options the patients might be offered are bypass surgery or angioplasty.  So let’s look at what is done in the bypass surgery. Now, we know the problem is lack of blood flow beyond the blocked artery. So what is done in bypass surgery is they open the chest. It is a major surgical procedure, which does have a lot of complication and risk. The chest cavity is opened and they take a graft or a vein or artery either from your leg and it called as a saphenous vein graft or it is an artery which is taken from the chest called internal mammary artery graft.

These grafts are positioned so that the blood can detour through these vessels and supply the area with lack of blood supply. So it can able to restore the blood supply to the area which is deficient because of the blockage in the coronary artery.  Once the blood flow is restored the patient’s chest pain comes down and he can walk more distance. Now for some patients, the cardiologist offers what we call is an angioplasty procedure.

EECP Therapy in Clinical Practice: A Modern Approach to Heart Care

  Heart treatment is evolving beyond the operating room. While surgery and stents remain vital, non-invasive options are expanding how we manage chronic cardiac conditions. Today, more people are turning to treatments that are safe, effective, and easier on the body. One such option steadily gaining attention is Enhanced External Counter Pulsation (EECP) therapy. If you have never heard of it, you are not alone. EECP does not make headlines, but it’s helping many patients, especially those with angina who have tried everything else. It offers relief without insertions, stents, or hospital stays. What makes EECP different is its ability to improve blood flow naturally, giving the heart the support it needs without surgery. It is designed for patients who want better heart health but prefer a smoother approach. In this blog, we will explain how EECP works, who it is for, and why it's gaining traction in modern cardiology. Clinical Foundations of EECP Therapy- An Overview ...

EECP Therapy: A Non-Invasive Solution for Angina and Other Heart Conditions

  Chest pain does not always arrive with intensity or warning. At times, it begins with little discomfort during a morning walk or heavy breathing that arises while climbing stairs. For many, these early signs are blamed on age, stress, or fatigue. But, over time, the episodes grow more frequent, becoming a pattern. This is often how angina surfaces, a symptom that signals the heart muscle is not receiving enough oxygen-rich blood. It’s a warning that should not be ignored. Traditionally, such symptoms lead to invasive procedures like angioplasty or bypass surgery. However, not all patients are eligible or willing to undergo surgical intervention. This growing gap between symptoms and solutions has led to the rise of an alternative therapy. It is non-invasive, clinically proven, and designed to support the heart’s natural ability to heal. This is where Enhanced External Counterpulsation (EECP) offers a proven, non-invasive alternative for managing chronic heart conditions l...

Is a Heart Attack the Same as Heart Failure

  If you’ve ever found yourself wondering whether a heart attack and heart failure are the same thing, you’re not alone. Many patients, even some caregivers, use the terms interchangeably. After all, both sound serious, both involve the heart, and both can be life-threatening. But here’s the truth: a heart attack and heart failure are not the same. They are very different events, with different causes, consequences, and treatment approaches. The difference is important to understand because it will allow you to make more informed choices regarding your own health or the health of someone you love. The Common Mix-Up: Why It Happens It's understandable why the terms become confused. Both illnesses involve coronary artery disease, and both may cause fatigue, shortness of breath, and hospitalization. But then the resemblance ends. A heart attack is typically something abrupt. It's almost as if it springs out of nowhere like a crisis. Heart failure, however, is a chron...
