Coronary artery disease or CAD is the name given to the heart condition in which the major blood vessels that supply your heart with blood, oxygen and nutrients, also called coronary arteries, get blocked, damaged or diseased.

Blockages usually happen when cholesterol-containing deposits called plaque deposit in your arteries. Plaque narrows the lumen of your coronary artery which means your heart gets lesser and lesser oxygen and nutrients to function properly.
Inflammation is also to blame for coronary artery disease.
Common symptoms of CAD include

Angina or pain in the chest
Shortness of breath
If the blockage is complete, you can get a heart attack.
Common Diagnostic tests
When you go to a heart specialist, she will ask questions about your medical history and follow it up with a physical exam and order routine blood and diagnostic tests to confirm CAD like:

Electrocardiogram (ECG): An ECG records electrical signals as they travel through your heart revealing evidence of a previous heart attack or one that s happening. Holter monitoring is a type of ECG where you wear a portable monitor for 24 hours as you go about your normal daily activities. Abnormalities in the results suggest reduced blood flow to the heart signaling CAD.
Echocardiogram: This test uses sound waves to produce images of your heart. It helps your doctor determine whether all parts of your heart wall are contributing to your heart's pumping activity. If certain parts are moving weakly it can mean damage to muscle due to a heart attack or because of receiving too little oxygen- again signaling CAD.
Exercise Stress test: This test is done by making you do exercises like walking on a treadmill or riding a stationary bike during an ECG. Sometimes, medication to stimulate your heart may be used instead of exercise.
This again detects areas in your heart that receive less blood flow.

Cardiac catheterization or angiogram. A special dye is injected into your coronary arteries to observe blood flow through your heart in a test known as an angiogram.
The dye is sometimes also injected into the arteries through a long, thin, flexible tube called catheter that is threaded through an artery in your leg to the arteries in your heart. This procedure is called cardiac catheterization. This test is very good in diagnosing CAD as the dye outlines narrow spots and blockages on the X-ray images of your heart.
Heart scans. Computerized tomography or CT can help your doctor actually see calcium deposits in your arteries that can be narrowing your arteries. If a substantial amount of calcium deposits are found, coronary artery disease could be the reason.
MRI scans are also done to diagnose CAD.

Common Tests For Coronary Artery Disease!

The heart is a muscular organ that pumps blood to the entire body through a network of arteries and veins. This network contains big vessels which branch out further to supply blood to the distant organs. There is, therefore, some pressure that the heart and thereby the vessels need to exert to push the blood through these vessels. This is known as blood pressure, and normal pressure levels range from 90-140(systolic)/60-90(diastolic) mm of Hg. However, due to various reasons, this pressure could be more, which is one of the first signs of heart disease. 

Causes of increased blood pressure: 

Thickening of the blood vessels. With age, the elastic blood vessels naturally turn rigid and less elastic, so there is more pressure required to push blood. It is natural for people over 55 years of age to have higher readings of blood pressure. This is known as primary hypertension (HTN) 
Narrowed blood vessels. This happens due to cholesterol accumulation along the walls of the blood vessels. Faulty dietary habits along with sedentary lifestyle have increased the incidence of hypertension due to this condition, known as atherosclerosis. Critical atherosclerotic narrowing of renal arteries lead to renovascular HTN that is one of the commonest of secondary HTN. 
Other Causes of secondary hypertension are: 

Kidney problems 
Thyroid hormone disorders 
Congenital heart defects 
Chronic alcohol abuse 
Adrenal gland tumours 
Chronic use of medications like birth control pills, pain killers, etc. 
Unidentified and uncontrolled hypertension can be silent and can lead to more severe conditions like heart attack and stroke. India is fast becoming the new hypertension capital of the world. Some of the common risk factors are: 

Age 
Family history 
Being obese or overweight 
Sedentary lifestyle 
Smoking 
Alcohol consumption 
Excessive salt intake 
Stress levels 
Ethnic background 
Symptoms: 

Hypertension can go undetected for years together, but if there are risk factors like diabetes and high cholesterol, it is advisable to periodically monitor blood pressure. 
Headaches, nosebleeds, and shortness of breath should not be ignored. These can be the first warning signs of hypertension, and if detected early, preventive measures can be taken. 
If there are co-morbid risk factors, it is advisable to constantly keep a check on BP readings. 
Management: 

This includes a combination of diet and lifestyle modifications. 

Quit smoking and alcohol: Of the many wonders quitting smoking can do, reducing BP readings is just one. The improvement would be almost instantaneous. Quit or else reduce alcohol and see dramatic improvements. 
Weight management: Through a combination of diet and exercise, ensure that weight is brought under control. Set a target BMI (Below 26 kg/m2) and work towards it religiously. 
Diet: Reduce salt, increase potassium, increase vitamin D, eat a heart-healthy diet, and see the hypertension readings improve. Please find attached and reviewed copy for health tip for posting

High Blood Pressure - All You Need To Know About It!

Cardiomyopathy includes diseases involving the heart muscle. These diseases have various causes, types, symptoms and modes of treatment.

The heart muscle gets enlarged, thick or rigid. In several cases, the heart muscle tissue is replaced with a scar tissue. As this condition worsens, the heart gets weaker and the ability to pump blood is disrupted, which can cause heart failure or irregular beating of the heart. The weakened state of the heart can lead to valvar diseases.

The different types of cardiomyopathy are:

 Hypertrophic cardiomyopathy-
This is a common form and affects people of all ages. Men and women are affected equally. This condition arises due to the enlargement and thickening of the heart muscle. The ventricles, the septum and the lower heart chamber usually thicken, which causes obstruction in pumping of blood by the heart. This disease also causes stiffness in the ventricles, and cellular changes in the tissue.
 Dilated cardiomyopathy-
This form of cardiomyopathy develops due to the enlargement and weakening of the ventricles. The issue arises from the left ventricle and develops over time. It may even affect the right ventricle. More effort is put in by the heart muscles for pumping blood and slowly the heart is unable to pump blood effectively. This condition may lead to heart failure, valve diseases or blood clots in the heart.
 Restrictive cardiomyopathy-
This disease occurs due to the stiffening of the ventricles, without thickening of the walls of the heart. The ventricles are not allowed to relax and do not receive a sufficient volume of blood supply. This condition causes heart failure and valvar problems over time.
 Arrhythmogenic right ventricular dysplasia-
This rare form of cardiomyopathy occurs when fat or fibrous tissues replace the muscle tissue of the right ventricle. This causes arrhythmias and disruption in the electrical signals of the heart. It generally affects teens and may cause cardiac arrest in athletes.
 Unclassified cardiomyopathy-
Some types of cardiomyopathy of this category include left ventricular non compaction where the ventricles develop trabeculations. Takotsubo cardiomyopathy is another disease where immense stress causes failure of the heart muscles.

Treatment-
Many cases of cardiomyopathy come and go away on their own. Treatment for other cases depends on the severity and symptoms. The major treatment methods are:
Lifestyle changes meant for a healthier heart.
Medication.
Nonsurgical methods.
Surgery and implants

Modes of surgery for treatment of cardiomyopathy include:
Septal myectomy
Heart transplant
Implant devices such as cardiac resynchronization therapy (crt) device, implantable cardioverter defibrillator (icd), left ventricular assist device and pacemakers are fitted into the heart for better performance.

Cardiomyopathy can be of many different types, each arising from different situations and conditions. The mode of treatment depends on the severity of the complication or on the basis of symptoms.

Types and Treatments of Cardiomyopathy

Commonly people believe that you can understand your blood pressure is high if you are feeling dizzy suddenly or you are not able to sleep at night. Also sweating profusely is often related to having hypertension. But, to be honest, hypertension usually does not have any symptoms, which might help you get alert and take action to control it. This actually imposes a great threat to your well-being as you do not understand if you have hypertension. It is extremely important for you to keep checking your blood pressure level in order to avoid developing hypertension and hence developing a risk to your heart.

Although there aren't any major or very noticeable symptoms, here is a list of some rare symptoms which you can follow:

1. Headaches: If you are suffering from dull headaches almost regularly, it might be because you blood pressure has increased. The headaches can be a dull buzz or a severe migraine like ache. Keep monitoring your headaches and consult your doctor as soon as possible.

2. Dizziness: You might suddenly feel dizzy or you might feel you are about to pass out if your blood pressure increases. Make sure you refer to a doctor as soon as something like this happens.

3. Nosebleeds: A sudden occurrence of nosebleed might also be a symptom of a sudden increase in your blood pressure.

4. Severe anxiety: Severe anxiety or a panic attack is often referred to as a symptom of hypertension. If you have a sudden panic attack with no apparent reason, it may be because your blood pressure has suddenly risen.

5. Shortness of breath: High blood pressure may often cause a shortness of breath. You might experience it during various every day activity like walking, climbing stairs, etc.

6. Nausea: A sudden increase in blood pressure might make you feel nauseous. You might even vomit when this happens. Make sure you consult your doctor if this happens.

Hypertension: Symptoms that Can Control it on Time

Symptoms of heart attack

A heart attack (myocardial infarction) should not be confused with stroke or heart failure. It is the condition which causes major damage to heart muscles because of sudden blockage by a blood clot. The most common symptom of heart attack happens to be chest pain. Heart failure and ventricular fibrillation are probably the most common complications in this condition. 

Clear symptoms of heart attack are:

1. Feeling vaguely ill - very vague feeling of illness is one symptom. You cannot really put your finger on what is wrong with you, but you do feel unwell.

2. Pain in left arm - pain in the arm, mainly the left arm is also one of the symptoms of an impending heart attack.

3. Sweating and heartburn - a lot of people have reported experiencing sweating, indigestion and heartburn before a heart attack. If you are sweating profusely and without any particular reasons, or having an unbearable heartburn, consult a medical specialist immediately.

4. Chest pain - feeling of fullness or tightness in the chest followed by pain is also a symptom of a heart attack. A lot of people have reported to ignore it; kindly don't.

5. Breathlessness - sudden shortness of breath and inability to do a lot of work at one point of time is not a good thing. This could be an indication of a heart attack.

6. Silent attack - the scariest of all is silent heart attack. At times, it comes with no symptoms at all. A person could be visibly physically fit, and suddenly have an attack. This usually happens with those who are suffering from diabetes mellitus.

All You Need To Know About Heart Attack Symptoms

Your diet plays a major role in the health of your heart, so eating healthy should be somewhere on the top of the list for keeping your heart healthy as well. There are numerous heart disorders that occur due to unhealthy food patterns and consumption. Lifestyle factors are the major causes of heart disease, and diet occupies an almost compelling spot when lifestyle factors are taken into consideration. Here is a list of foods that keeps your heart healthy:

Salmon: Omega-3 fatty acids are very important for your heart to function optimally. Fishes such as salmon and sardines are rich in omega-3 fatty acids which lower the risk of heart diseases such as arrhythmia (irregular heartbeat) and atherosclerosis (accumulation of plaque in the arterial walls).

Oats: Like oats and milk for breakfast!? Congratulations! You are in luck; oatmeal has soluble fibers which help in lowering bad cholesterol levels. Just make sure that there is no added sugar in your oatmeal, as it will defeat the entire purpose.

Blueberries: Blueberries are rich in antioxidants that reduce the risks of heart attack and also decrease your blood pressure. So go ahead! Toss some blueberries in your oatmeal to get your daily dose of antioxidants which are such pre-requisites for supreme health.

Dark Chocolate: This will probably bring a smile to your lips. Dark chocolates contain polyphenols, a type of flavonoid, which is very good for your heart. Dark chocolate is known to reduce the risks of strokes and heart attacks. Watch the portion size as no matter what its benefits are, dark chocolates are still rich in calories.

Citrus Fruits: Citrus fruits such as lemons and Indian gooseberry are rich in compounds that lower cholesterol levels in the body. Tip   Start your day with a lemon juice and warm water. This betters your metabolism and also keeps your heart in fine shape.

Soy: Lo Behold Vegetarians! (and non-vegetarians as well). Soy is a protein rich food that is so good for your heart. It also contains heart-healthy fats and fibers that help bring down and normalize cholesterol levels.

Tomatoes: Tomatoes are rich in an antioxidant called  lycopene , which is very effective in getting rid of bad cholesterol. It thus helps in keeping your arteries healthy and reduces the risks of heart attacks.

Nuts: Nuts such as almonds and walnuts are rich in Vitamin E which helps in lowering bad cholesterol in the body. Avoid nuts that come with added salt.
