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!

Cholesterol is generally regarded as something bad for the health. As a part of diet, everyone tries to avoid anything that has cholesterol in it. What needs to be understood is that not all cholesterol is bad. There is also good cholesterol, which is actually very essential for body functions. This is required for the production of essential hormones. Inadequate amounts of good cholesterol can lead to problems ranging from simple hormonal imbalances to severe issues like infertility.

The following are some food items, which contain sufficient amounts of good cholesterol and should find a place in your plate. They are essential for various body functions including hormone formation.

Avocado oil: Most oil is considered bad, but avocado oil contains about 70% of good cholesterol and should be used for its heart-healthy benefits. Being a great antioxidant, it protects the heart by reducing inflammation and by improving blood pressure. Eating whole avocado is also beneficial for the heart and the body as a whole.

Buckwheat: This whole grain is rich in many vitamins, quite a few minerals, and is a good provider of dietary fiber. It is also gluten-free and is rich in antioxidants, making it extremely cardio-friendly.

Soy: Too much saturated fat in the diet cannot be digested and the liver converts these and stores it, which adds to obesity. Soy which is a good replacement for animal fat and even dairy products can help improve cholesterol levels and prevent fat accumulation.

Salmon: This is one of the most heart-friendly food items, which is loaded with omega-3 fatty acids and good cholesterol. It lowers triglyceride levels and provides a good amount of protein for the body.

Spinach: The cholesterol which settles against the blood vessels is washed off by consuming spinach   in regular quantities at regular intervals. It is also the richest source of lutein, which is known as guardian against aging diseases including hypertension.

Go the nutty way: While most would consider nuts as rich in oils, truth is they are loaded with good cholesterol. Therefore, whether it is almonds or pecans, ground nuts or walnuts, nuts are great for the heart. They are also rich in minerals including calcium, copper, magnesium, and potassium and contain various vitamins. So about a teaspoon of chopped nuts should be on your plate on any given day.

Dark chocolate: Again, like nuts, most of us tend to avoid chocolate, but these restrictions are only for the white ones with sugar. The dark one is extremely healthy for the heart with loaded antioxidants, which prevents clogging of arteries. It is also rich in flavonoids, which are useful in controlling blood pressure and other heart diseases.

Low Cholesterol Diet - Seven Food Items To Try!!

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!

Psychogenic breathlessness or pseudo-dyspnea is a condition where the patient suffers from shortness of breath time to time. This disease is often confused with a similar breathing disorder called Chronic Dyspnea. While there are a lot of factors involved in chronic dyspnea, like allergens and pulmonary diseases, psychogenic breathlessness has more to do with the current state of mind.

One of the most challenging factors is the diagnosis and differentiation between both conditions. Sometimes, the psychogenic breathlessness is so concentrated that there is no way to differentiate between the two.

Procedure of Diagnosis of Psychogenic Breathlessness:

Here are the steps that doctors typically follow to diagnose Psychogenic Breathlessness

To differentiate between the two diseases (Chronic Dyspnea and Psychogenic Breathlessness), the doctor will ask the patient to try breathing harder. A patient with chronic dyspnea will find it even harder to take a breath when he or she tries to. However, a person with psychogenic dyspnea will show improved conditions when they try to breathe harder

A thorough examination of the chest will be done

Blood tests and lung function test (spirometry) will also be conducted to rule out pulmonary diseases

Causes of Chronic dyspnea:

Allergens causing allergic bronchitis (also known as asthma) is the main reason behind Chronic Dyspnea. Other common causes of the true or chronic dyspnea are heart diseases, COPD which occurs because of smoking. Then there are rare disorders like ILD (sarcoidosis), neuromuscular diseases, infections, anemia, obesity/deconditioning.



Causes of Psychogenic dyspnea or psychogenic breathlessness:

Acid reflux: Acid reflux can cause certain sensation on the inner lining of the esophagus (esophagitis). The esophagus has several nerve endings on the inner linings, when the acidic reflux touches these nerve endings, a temporary breathlessness occurs.

Anxiety: People with anxiety can also develop breathlessness. Though exercises help for a short period of time, a patient needs to see a psychiatrist for this condition.

Panic Attacks: These are also a cause for breathlessness. The temporary feeling of choking is common in people who experience panic attacks.

Treatment:

Medication: Medicine for acidity is prescribed to patients having Pseudo-Dyspnea, due to acid reflux.

Anxiety pills and Talking therapy: People suffering from anxiety are recommended to see a psychiatrist for better evaluation of their problem. Medications (anxiety pills) prescribed by the psychaitrist may help in controlling the breathing pattern in a person. Psychological therapies (Talking therapy) have been effective for people suffering from breathlessness due to anxiety.

Placebo: If the problem remains unsolved and unknown, sometimes doctor prescribes placebo medication, for example sweetened aerosol. Doctors believe that if the patient thinks he/she is taking a real medication, his/her condition can be controlled by eluding the mind.

It is important to remember that Psychogenic Breathlessness is as real as chronic breathlessness and patient doesn t pretend to have this condition. When the first symptoms of it start appearing, a specialist doctor (pulmonologist) should be consulted who after confirming the diagnosis of psychogenic breathlessness, may refer you to a psychiatrist or psychologist for further treatment.

How many of us have heard about Extracorporeal Membrane Oxygenation (ECMO) before Tamil Nadu, Chief Minister late J Jayalalithaa was put on it for recovery? Hardly a handful. Patients who are placed on the device have 50-50 chance of survival and while it could not help the late Chief Minister, her condition put a spotlight on ECMO.

What is ECMO?
ECMO is a life support device that is put in place when a patient's heart and lungs stop functioning completely post a cardiac arrest. When the patient does not respond to Cardio Pulmonary Resuscitation (CPR), the patient is put on ECMO.

Function of ECMO
The core function of the device is to separate carbon dioxide from the blood and add oxygen into it. It takes the load off from heart and lungs, providing critical time to the body organs for its treatment and recovery.
Patients are only put on ECMO, if there is a chance that the condition can be reversed.

How does ECMO work?
The device drains blood from a vein, which is attached to an oxygenator machine. The machine then removes carbon dioxide from the blood and adds oxygen to it. Depending upon the condition of the patient, the warm blood is either pumped into the body with the help of the machine or is transferred back into the body through an artery.

How long a patient can be on ECMO?
After seven days of being put on ECMO,there are chances of patient getting an infection.
In case the patient contracts an infection, it is recommended to take the patient off ECMO support.

All About ECMO - Extracorporeal Membrane Oxygenation 

Bradycardia is a condition which in basic terms means slow beating of the heart. In most cases, the typical rate is 60 to 100 beats in a minute when the person is at rest. In case your heart beats less than 60 times in a minute, then it is slower than normal. But a slow heart rate is not always a health concern even though sometimes it could indicate issues with of the heart.

What could bradycardia mean?
Some people with slow heart rate or bradycardia tend to be very fit, and they have no underlying health issues. Athletes and healthy young adults often have a heart rate lower than 60. But in others, bradycardia indicates that the natural pacemaker of the heart is not working well, or the electrical pathways have been disrupted. In severe forms of the problem, the heart may beat so slowly that it fails to pump adequate blood for meeting the needs of the body. This may show some symptoms and could be fatally dangerous.

What are the causes of bradycardia?
There are various causes of bradycardia, and some of them include:

Alterations in the heart which results from aging
Health conditions that slow down the electrical impulse through the heart. This may include electrolyte imbalance, low thyroid levels, and others.
Diseases which may disrupt the electrical system of the heart including heart attack, coronary artery disease, and myocarditis.
Certain medications that are used for treating heart problems like high blood pressure or hypertension, arrhythmia, and beta-blockers, and digoxin.
What are the symptoms of bradycardia?
When a person has very slow heart rate, he or she may experience lightheadedness or dizziness, feeling short of breath, having difficulties in doing normal activities or exercising, having chest pain, feeling tired and fatigued. In some cases, it is seen that the person may have palpitations, feeling confused, trouble in concentrating and fainting.

What s worse, some people don t have any symptoms at all, or their symptoms are so negligible that they think they are caused just because of aging. The best way to understand whether you have this problem is to take the pulse, and in case, it is slow or uneven, you must talk to a doctor.

How is bradycardia diagnosed and treated?
Bradycardia tends to come and go from time to time, and therefore, a standard EKG is not always able to detect it. A standard ambulatory electrocardiogram is used for detecting the condition, and sometimes, blood tests are also necessary.

The treatment of bradycardia is entirely dependent on the cause of the problem and its symptoms. It is worthy of mention here that in case the problem is not causing any symptoms, then they would not be treated under usual circumstances.
