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.

What Happens When the Electrical Activity of Your Heart Changes?

The heart's electrical conduction system plays a very important role in cardiovascular functioning. Also known as the atrioventricular (AV) conduction system, it regulates and controls the timing of the heartbeat.

How does the heart's electrical conduction system work?

There is a collection of electrical cells in the upper right atrium of the heart known as the sinoatrial (SA) node which acts as a natural pacemaker and generates electrical signals. These signals travel through specialized electrical pathways and stimulate the muscular walls of the heart to contract in a rhythmic manner. This gives rise to the heartbeat that pulses at a specific frequency every minute.

What is the effect of fluctuations in electrical activity on the heart?

The standard heart rate in human being ranges from 60 to 100 beats per minute. It slows down when a person sleeps and speeds up when one experiences physical or emotional heightening. These fluctuations are triggered by the brain or other systems of the body and signal the SA node to generate charges more rapidly or slowly. This leads to spikes and drops in the heart rate, depending on the nature of the situation.

What happens when there is dysfunction in the heart's electrical activity?

When the heart's electrical conduction system does not function properly, it leads to the occurrence of a condition known as arrhythmia or abnormal heart rhythm. This happens when electrical impulses are generated in an irregular manner and causes tachycardia (rapid heartbeats) or bradycardia (slow heartbeats) which takes place in jarring infrequent tempos.

What causes fluctuations in the heart's electrical activity?

There are various kinds of triggers that cause the heart rate to fluctuate. The exact nature of fluctuation also depends on the type of trigger. A few everyday examples of these causes are as follows:
- Exercise and strenuous physical activity increases electrical activity as the heart is required to beat faster so as to increase the supply of blood and oxygen to the muscles.
- Sleep and rest reduce heart rate as the body is not needed to exert itself.
- Release of adrenaline into the bloodstream causes the heart rate to spike up.



What Happens When the Electrical Activity of Your Heart Changes?

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.
