Heart Blocks are a result of plaque buildup in your arteries, which blocks blood flow and circulation to the heart, causing heart muscle damage and heightens the risk for heart attack and stroke.
Arteries which have smooth and elastic walls become thick and restrict blood flow from the cholesterol deposits over the years. Blood clots can also block the arteries that supply oxygen rich blood to the heart. These can eventually lead to strokes and heart attacks.
Some warning signs that you may be at risk of heart blockage:
- Have you had a mild stroke: Plaque that accumulates in the carotid artery supplying oxygen rich blood to the brain can cause a stroke. People who have had strokes are more prone to heart attacks.
- Do you often feel fatigue and dizziness: Reduced oxygen from poor circulation and blood flow can result in fatigue and tiredness as well as dizziness.
- Experiencing shortness of breath: Poor blood flow can lead to shortness of breath from even mild forms of exercise or even from carrying out daily chores or walking.
- Sudden chest pain: Chest pain or angina result from reduced supply of blood to the heart. It can be felt as pressure, tightness in the chest, squeezing in the chest, numbness or burning.
- Unexplained lower back pain: This can result from pressure in the spine as a result of pinched nerves due to compressed vertebrae discs as a result of poor blood flow.
- Erectile dysfunction in men: If an erection becomes difficult or impossible, it could be a warning sign of clogged arteries. These arteries supply blood to the pelvis area and help achieve an erection.
- Calf pain: Blocked leg arteries can cause calf pain, especially in smokers . THis is an early sign of possible heart blocks.
- Painful, numb and cold hands and feet: Plaque build up in the arteries of the extremities can cause numbness and coldness in the hands and feet.
Remember early detection is the key to prevent or delay heart attacks.

Blockage in heart is a common term used for narrowing of coronary arteries. Coronary arteries are vessels, which supply blood and thus oxygen and food to continuously working heart muscles. Heart muscles, which are not tired working from the birth till death, however, cannot sustain long without blood supply.
A reduction in blood supply gives rise to ischemia of heart muscles commonly manifested as chest discomfort or angina. A sudden complete shutdown of blood supply leads to heart attack leading to permanent damage to heart (if blood flow not reestablished promptly).
But what causes these arteries to block? Deposition of LDL cholesterol (low density cholesterol) in inner surface of coronary arteries is the primary reason of these blockages. LDL a normal component of blood (upto certain limit) starts depositing in arteries as early as 10 years of age!
Deposition of billions of LDL molecules over several years on inner surface of arteries gives rise to visible narrowings in these arteries. Flow ahead of these narrowings is reduced in proportion to the narrowing. At a level of 70 % narrowing the flow is reduced to give ischemia (and angina) during exercise. Gradually increasing degree of narrowing reduces the exercise needed for ischemia and angina; a narrowing of more than 90 % can give symptoms at rest. A sudden clot formation at any of these stages can block the flow suddenly giving a heart attack.
If LDL is a normal component of blood, why it is deposited in the arteries at first place?
LDL above a certain limit in blood starts depositing in the arteries. Diabetes, Hypertension, smoking, less exercise and genetics makes it more sticky thus making narrowing faster. This is why these risk elements need to be properly attended for prevention from heart disease.
For treatment medicines are important for stopping the progression of narrowings; angioplasty is a method of fast resolution of blockage; and bypass surgery is the method of creating a whole new blood supply for the affected part of the heart.
A sudden cardiac arrest is not same as a normal heart attack. While a heart attack refers to the blocking of blood flow to the heart, a sudden cardiac arrest refers to when the heart stops beating unexpectedly. Sudden cardiac arrests occur without warning and often this condition is triggered by electrical malfunctioning in the heart that causes arrhythmia.
When the heart stops beating, blood cannot be pumped to the brain and other organs and the person loses consciousness. If a patient does not receive immediate treatment, this could be fatal. Hence it is important to know what first aid a person experiencing a sudden cardiac arrest requires.
Do not wait for someone else to help a person experiencing a sudden cardiac arrest. The first few moments after such an experience are critical and hence your decision to help is what could save the person’s life.
Call a Doctor
The first thing to do when you see someone experiencing a cardiac arrest is to call emergency and request an ambulance. If you do not have a phone available, ask someone else to do it.
After a cardiac arrest, it is essential to get the heart to start beating again as soon as possible. CPR or Cardiopulmonary resuscitation can save lives in this situation. If you are trained in this procedure, start with 30 chest compressions before checking the patient’s airway and performing rescue breathing. If you are not trained in CPR, ask the people around if anyone else is.
If no one around can perform CPR, start hands-only CPR. Make the person lie flat on their back and kneel next to their shoulders. Place the heel of one palm in the centre of the person’s chest with the other hand over it. Keep your elbows straight and position your elbows such that they are directly over your hands. Use your upper body weight to push down straight on the person’s chest and release. Try and achieve a rate of 100 compressions a minute. Continue until the person starts breathing again or medical help arrives.
Use an Automated External Defibrillator (AED)
If an AED is available, place the electrode pads on the person’s chest as shown in the diagrams that come along with the AED. Follow the visual and voice prompts. Do not worry if the AED shocks the patient as this electrical therapy can help restart the heart.
Angioplasty is referred to as a cardiac procedure, which involves widening the narrowed section of a coronary artery. Usually performed by an interventional cardiologist, this procedure is performed in a cardiac catheterization lab, short for a cath lab. An interventional cardiologist takes extra care to review the risks, in addition to obtaining your counsel prior to preparing you for the procedure. The physician also refers to your medical history in order to determine the amount of anesthesia that should be used.
What happens during the procedure?
Although mild sedatives will be administered to help you relax, the process requires you to remain awake throughout the procedure. The procedure of angioplasty involves cardiac catheterization. The doctor numbs the intended site through medications and inserts the catheter. Following such the doctor inserts a thin sheath in your artery, oftentimes in your groin or arm. A long, narrow, empty tube known as a catheter, is then carefully guided through the sheath, through the blood vessels and into the arteries near the heart.
A little amount of liquid is then injected through the catheter, which is moved through the chambers, valves and vessels of the heart. This movement is then pictured with the help of X-rays, with which the doctors can diagnose the condition and working of the coronary arteries and the heart valve.
The surgical procedure lasts for around 1.5 - 2.5 hours, but the preparation and post - surgical procedures may take several hours. A patient is usually made to stay overnight to be monitored by medical personnel.
What to expect before an Angioplasty?
Most people are made to undergo a blood test and electrocardiogram before having an angioplasty. Usually scheduled a day before the procedure, such tests usually require separate appointments. Usually patients are restricted to eat since 12 hours before the exam.
What happens post-procedure?
After the procedure, you will be instructed to remain flat for 5-6 hours without bending your legs, so as to prevent bleeding. The nurse will instruct you as to when you can get up from your bed. You may not be permitted to drink or eat until the groin sheath is removed as such can cause nausea.
According to the procedure, the doctor will provide you with adequate after care advice.
Our survival is solely reliant on the working of the heart. It is this that makes the prospect of a heart failure so fatal and so terrifying. Notwithstanding what the heart evokes, a heart failure is not indicative of a defunct heart; but only a situation when the heart pumps weaker than what is generally deemed as natural. Consequently, the blood flows at a slower rate to the heart and the body that in turn increases pressure in the heart. The oxygen that is produced by the heart in such a scenario is scanty and insufficient for the body.
body responds with its own defense mechanism, as the heart, in an attempt to hold more blood, stretches its chambers. Though this strenuous effort may keep the blood moving, it would gradually and inevitably weary the heart with all the effort. Subsequently, the kidney responds by retaining more salt and fluid in the body. These fluids may accumulate in different parts of the body, mainly in the legs, feet, ankles leading to congestion in the body. This very condition in medical terminology is referred to as congestive heart failure.
Different causes can contribute to the onset of such a fatal condition. Some of them are
- Coronary artery disease: In such a condition, the arteries supply insufficient amount of oxygen and blood to the heart. Subsequently, the heart receives scanty amount of nutrients and oxygen.
- Heart attack: The sudden, unanticipated blockage of the coronary artery and the ensuing stoppage of the flow of the blood lead to a heart attack. The heart muscles are damaged in such a case and prevent the proper functioning.
- Diseases: Though the term may be generic and over expansive, most of the ailments which people suffer from tend to manifest themselves by posing a potential threat to the functioning of the heart. A high blood pressure, kidney disease, even a thyroid disease can cause congestive heart failure.
Every disorder is preceded by certain symptoms, and congestive heart failure is no different. Some of them are
- Fatigue: This is one of the most perceptible symptoms of congestive heart failure. One of the earliest premonitions of an impending heart failure is a nagging sense of weariness and lethargy.
- Swelling: As the condition is characterized by accumulation and build-up of fluids in various part of the body, swelling is an inevitable symptom of this condition and a clear indication of the ailment.
