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!

Heart attack, also known as myocardial infarction, is a severe condition where death of the heart muscle occurs because of the loss of blood supply. The blood loss usually happens because of the blockage of a coronary artery. Due to electrical instability, ventricular fibrillation is caused. Heart attacks may result in permanent brain damage or even death.

Symptoms of heart attack
There are many early symptoms and signs of heart attack, which should be recognized. Symptoms of heart attack vary from person to person. Here is a list of the primary heart attack symptoms:

Chest pain and discomfort:
Chest pain is the basic symptom of a heart attack and occurs in different forms. The chest pain has a pressure, fullness and squeezing sensation and starts from the center of the chest. The pain may go away and re-occur and may spread down to other limbs of the body.
Headache, toothache:
The chest pain occurring due to a heart attack spreads all over the body and the jaw. Even the back and head are affected. Sometimes pain in these regions is present while chest pain is absent.
Shortness of breath:
A gasping sensation or feeling shortness of breath is another common sign of a heart attack. Such breathing difficulty is called dyspnea. The shortness of breath occurs before or during the chest pain.
Nausea and vomiting:
The feeling of nausea or sickness in the stomach is another possible symptom. It is accompanied by belching or burping and sometimes, the heart attack is associated with a feeling of indigestion. Nausea is more common in women. Vomiting also occurs alongside nausea.
General epigastric discomfort:
In several cases, patients describe the pain of a heart attack as stomach pain. The pain is heavy and uncomfortable and persists for several minutes.
Sweating:
Perspiration or sweating occurs during a heart attack and the patient experiences cold sweat in avid amounts.

Emergency treatment for heart attack-
A person who has a heart attack should be rushed to a hospital.
Several tests are carried out to detect the cause of the attack. A 12 lead ekg is carried out to supervise electrical activity within the heart and detect the damaged areas.
Blood tests are undertaken to check enzymes and in certain cases, cardiac catheterization is required where pictures of the blood vessels are examined.
Emergency medicines are given to the patient to stop the formation of blood clots and include aspirin, heparin and other drugs. Other medicines are given for thrombolytic therapy, which dissolve already formed blood clots. They work to reduce the heart damage. Nitrates are also used.

A heart attack is a severe condition and must be attended to immediately. Emergency treatment procedures are essential to save the life of an affected person.

Heart Attack - Signs, Symptoms and Emergency Treatment

With recent lifestyle changes, more and more people, younger in age, are falling prey to heart attacks. While some silently suffer the attack during their sleep and never wake up, others have symptoms which they dismiss as acidity or muscular pain and ignore them. There are multiple media programs that are trying to create awareness about how to identify a heart attack. If done at the right time, there is a good chance that the person can be saved.

What is a Heart Attack?

The blood vessels gradually narrow, reducing the blood flow to the target organs. This reduces the efficiency of the target organ, and if this happens to be the heart, it is known as a heart attack. The area that should ideally receive blood does not, leading to its  death.  If the damage is not severe, it can be reversed. However, if this attack happens in one of the critical areas of the heart, it can even be fatal.

Symptoms To Watch For: Very few attacks happen suddenly. Most start slowly and progress, and if identified on time, a life can be saved. The episode takes about an hour, and if you are well-versed with the symptoms, it could help identify the condition correctly and save a life. Most people use antacids and muscle relaxants to ease the situation, which does provide immediate relief, but not a proper cure.

There is a central pain which is constant, nagging, and has a squeezing like sensation. This causes discomfort and most often, this pain is in the center of the chest area, which lasts for just a few minutes. Sometimes the pain can go and come back. This pain radiates down into the arm, up into the neck area, and also into the jaw and is almost always indicative of a heart attack.

With chest pain, there is always shortness of breath which the person will experience. This is due to reduced oxygen levels in the body.

Associated symptoms include fatigue, exhaustion, nausea, dizziness, light-headedness.

There is almost always profused sweating where the person breaks into a cold sweat.

If the attack happens during sleep, the person may be snoring and may feel, as if something is choking his airway.

Due to reduced return of blood from the peripheral organs, there could be swelling of the feet and ankles.

If there is irregular heart beat (palpitations) very often, talk to your doctor about it.

When you suspect a person of having a heart attack, check for these signs. Very often, a heart attack is detectable and can be managed with timely intervention.

Signs Of A Heart Attack

A discomfort in chest accompanied by shortness of breath and a tingling sensation in fingers or toes might be a sign of hyperventilation, more commonly known as panic attacks. This is the condition wherein you need more amount of oxygen than normal.

And, you need to be aware of the symptom, especially if you are suffering from COPD (Chronic obstructive pulmonary disease). With COPD, experiencing symptoms of hyperventilation may turn adverse, and there are enough reasons to know the ways to manage it, which is indeed possible.

Symptoms
Hyperventilating or over-breathing can be accompanied by or can cause various symptoms in people. Apart from the common symptoms described above, some patients may also experience dizziness, palpitations, sweating profusely, wheeze, feelings of suffocation or choking, tinnitus, weakness, etc. Some may also feel highly anxious or tensed. Though very uncommon, still, one may suffer from loss of consciousness as a result of hyperventilating.

Dealing with hyperventilation
Depending on the severity and type of hyperventilation, the available treatment option may vary from person to person. From various home remedies to certain prescribed drugs, treatments are available easily. However, it s through practicing a few techniques on noticing the symptoms that can help one deal with hyperventilation. Some of those useful methods are, breathing through pursed lips, holding the breath for 10 to 15 seconds, trying to take deep breaths into the belly rather than in the chest and breathing slowly into cupped hands or a paper bag. These techniques will help regulate the breathing.

Preventing hyperventilation



As with many conditions, being aware of the preventive measures is crucial to managing the symptoms and the same is true with hyperventilation as well. A few measures to follow by COPD patients to prevent hyperventilation
Wearing tight fitting clothes restrict normal breathing. Therefore, wearing clothes that are loose on the upper chest portion can assist in preventing over breathing.
Opting for light exercises regularly (approved by the doctors, as having COPD needs extra attention in activities) helps in reducing stress levels and anxiety, which again can play a crucial role in preventing hyperventilating.
Though initially, it may be difficult, still, one must try to breathe through his or her nose and close the mouth for preventing over-breathing, as closed mouth makes it extremely difficult to hyperventilate.
Further, sleeping well during the night, eating a balanced diet, reducing the intake of caffeinated beverages like tea and coffee, and practicing various techniques for relaxation can be helpful too in preventing hyperventilation.
In case, the episodes of hyperventilation last for more than 30 minutes, even after trying all the techniques mentioned above, one should not delay in seeking necessary medical attention.
Growing episodes of hyperventilation or over-breathing can leave one feeling breathless. Therefore, when people with COPD notice any symptom of hyperventilation, consulting with pulmonology specialist must be of top priority. Neglecting this particular condition for an extended period may end up causing further complications. In case you have a concern or query you can always consult an expert & get answers to your questions!

Hyperventilation - How COPD Patients Can Deal With It?

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?

Health experts do believe, and are promoting the same nowadays, that eating right is the best step to control high blood pressure other than regular medications. Who knows, if you are strong enough to control your lifestyle and eating habits, you may not need a long term medication after some time. The blood pressure may lower down naturally with improving health and weight.

Factors that elevate blood pressure in the body.

Before suggesting the right eatables for lowering the blood pressure, let s look at the conditions which actually increase the blood pressure. They are:

A coronary heart disease
Stress
Anxiety
Work pressure or family and relationship troubles
Obesity
Cholesterol
Other medical conditions like diabetes, depression, etc.
Pregnancy
Each one has a toll on the body with resultant High Blood Pressure. With eating right you may gain a lot of control on the body.

Eating Right

Here are some quick tips on eating right:

Avoid excess salt intake. The more salt you take, the more sodium your body gets, and as a result BP elevates. When you eat readymade snacks, packaged foods and drinks with preservatives, check the nutritional information. Most of them contain high sodium. You may stop the intake of such foods or restrict them completely.

Avoid oily and junk food. Avoid food with unsaturated or trans fats. These kinds of foods straightaway add to the fat deposits of the body, and make you obese or more obese. In such cases, the obesity and increased weight build a pressure on the heart to pump more, thus elevating blood pressure.

Avoid excess caffeine. Caffeine comes in the body through coffee, tea, and aerated drinks. These beverages when restricted to only 1-2 intakes per day may help you lower the BP.

Quit smoking, as this puts excess pressure on the lungs to breathe and thus the heart to pump.

Reduce alcohol intake: Avoid alcohol intake in excess amounts. Drinking more alcohol or frequent drinking can elevate blood pressure.

Besides there are some good foods that can always help to lower or control BP. They are:

Plain, fat-free yogurt or Greek yogurt
White beans
Pork tenderloins
Small fishes like Tilapia
Bananas
Oats
Broccoli
Bell Peppers
These food items are designed by nature to reduce blood pressure or normalize blood pressure in the body. Hence, if you are trying heart and soul to eat right, then try these in your daily food to see positive results. Besides, exercising and reducing weight are the two other important steps to take, which complement the healthy diet and eating habits to lower the blood pressure with or without medication.
