Congenital heart disease
Maladies cardiaques congénitales sont des anomalies du cœur de la structure et la fonction causés par des anomalies cardiaques ou souffrant de troubles de développement avant la naissance. Maladie cardiaque congénitale (CHD) est un terme général qui peut décrire un certain nombre d'anomalies qui affectent le cœur. Cardiopathie congénitale est, par définition, présente à la naissance même si ses effets mai ne pas être immédiatement évident. Dans certains cas, tels que la coarctation de l'aorte, mai il pas lui-même depuis de nombreuses années et quelques lésions telles que un petit défaut du septum ventriculaire (VSD) mai jamais causer de problèmes et sont compatibles avec l'activité physique normale et une durée de vie normale . Selon l'American Heart Association, environ 35.000 bébés naissent chaque année avec un certain type de cardiopathie congénitale défaut. Cardiopathie congénitale est responsable de plus de morts dans la première année de vie que les autres malformations à la naissance. Bon nombre de ces défauts doivent être suivis attentivement, même si certains guérir avec le temps, d'autres nécessitent un traitement Certaines maladies cardiaques congénitales peuvent être traitées avec des médicaments à lui seul, tandis que d'autres nécessitent une ou plusieurs interventions chirurgicales. Le risque de décès par cardiopathie congénitale chirurgie a diminué d'environ 30% dans les années 1970 à moins de 5% dans la plupart des cas aujourd'hui. Cardiopathie congénitale est souvent divisée en deux types: celles avec cyanose (décoloration bleu causé par un manque relatif d'oxygène) et ceux sans cyanose.

HEART STATISTICS
- Coronary artery disease is the single largest cause of morbidity amongst all diseases so much so that it has been classified as having reached pandemic proportions by none less than the WHO (World Health Organisation).
- Over 7,0000,000 Indians have heart related diseases
- 1 in 3 adults, both men and women, has some form of cardiovascular disease.
- In 90% of adult victims of sudden cardiac death, two or more major coronary arteries are narrowed or blocked.
- Brain death and permanent death start to occur in just 4-6 minutes after someone experiences cardiac arrest.
- The cardiac 64 CT scan provides 3D images of the heart so detailed that the heart disease can be detected at a very early stage.

Effects of Heavy Drinking on Heart Health Differs Between Genders
If you are like many Americans, you probably drink alcohol, at least on occasion. Previous studies have shown that moderate drinking (one drink a day for women or anyone over 65, and two drinks a day for men under 65) is probably safe, and may even have health benefits. However, heavy alcohol consumption can negatively affect almost every system in the body, and new findings indicate that women face greater risks to their heart health than their male counterparts.
A Japanese Collaborative Cohort Study, led by Dr. Hiroyasu Iso, professor of public health at Osaka University, followed 34,776 men and 48,906 women to analyze the effects alcohol consumption had on the different genders. The study participants, with ages ranging from 40 to 79, were followed for an average of 14.2 years. During that time, 1,628 subjects died from stroke and 736 died from coronary heart disease.

Low vitamin D level may up death risk
A new study has again linked low vitamin D levels with an increased risk of death. Austrian researchers say that in a study of 3,258 patients, those with the lowest vitamin D levels were twice as likely to die from heart disease and other causes as those with the highest levels. This study is the latest of several trials that have linked vitamin D to diseases such as cancer, diabetes, obesity, and hypertension.

Risk Factors Of Ischemic Heart Disease
Ischemic Heart Disease we can include people with personal or family history of:
heart attack (myocardial infarction)-when a part of heart muscle is permanently damaged or actually dies because there’s not enough oxygen.
unstable angina-is an intermediary between myocardial infarction and stable angina.It’s manifestation is a severe chest pain that lasts more than stable angina and it doesn’t respond very well to medication.
angina-is a chest discomfort which occurs when the coronary vessels receive an inadequate blood flow.
atherosclerosis-occurs when fatty material deposite into the arteries walls. This can lead to a blockage of the arteries.
Other risk factors for Ischemic Heart Disease are:
hypertension (high blood pressure)- blood pressure can vary with activity and with age, but a healthy adult who is resting generally has a systolic pressure reading between 120 and 130 and a diastolic pressure reading between 80 and 90 (or below).
diabetes-heart problems are the leading cause of death among people with diabetes, especially in the case of non-insulin-dependent diabetes also known as Type II diabetes.
high blood cholesterol-cholesterol is a fat-like substance carried in your blood.It can be found in all of your body's cells. The liver produces all of the cholesterol your body needs to form cell membranes and to make certain hormones. Extra cholesterol enters your body when you eat foods that come from animals (meats, eggs,and other similar products).
obesity and overweight- extra weight leads to increased total cholesterol levels, high blood pressure, and an increased risk of coronary artery disease. Obesity increases your chances of developing other risk factors for heart disease, especially high blood pressure, high blood cholesterol, and diabetes.
smoking- It’s well known that smoking increases the risk of lung cancer, but few people know that it also increases the risk of heart disease and peripheral vascular disease (disease in the vessels that supply blood to the arms and legs). Smoking also raises blood pressure, which increases the risk of stroke in people who already have high blood pressure.
birth control pills-At the beginning birth control pills contained high levels of estrogen and progestin, and taking these pills increased the chances of heart disease and stroke, especially in women older than 35 who smoked. In our days the dose of hormones contained in these pills has been lowered and they are considered safe for women younger than 35, who do not smoke or have high blood pressure.
physical inactivity- people who exercise regularly have a lower risk of heart attack than people who are not active. Exercise burns calories, may lower blood pressure and helps to control cholesterol levels and diabetes. In addition to this exercise makes the arteries more flexible and strengthens the heart muscle.

Health - Conditions - Drugs and surgery
Heart surgery
Sometimes medication can't control all the symptoms of heart disease. Surgery may be needed to open or replace the blocked arteries, repair damaged valves or simply keep the patient alive.
Common operations for heart disease include:
Coronary angioplasty
Coronary angioplasty, or percutaneous transluminal coronary angioplasty (PTCA) to give it its full technical name, is used to treat coronary heart disease.
It involves passing a long, thin, hollow tube or catheter up into the coronary arteries, under x-ray guidance, from an artery in the groin or arm (under local anaesthetic.) A device on the tube is then used to unblock the artery, and stretch the artery walls so that more blood and oxygen can flow to the heart muscle.
Angioplasty may be recommended if angina cannot be controlled with drugs, if angina is limiting a person's life, or when a person gets angina just sitting in a chair at rest.
PCTA may be performed as an emergency when someone is having a heart attack. If carried out soon enough it can open the blocked coronary artery before permanent damage is done to the heart muscle. But it can only be performed in a specialist hospital, so it's not an option for most people having a heart attack.
Types of angioplasty
Balloon angioplasty, often known simply as balloon treatment, was the first type of angioplasty. On the end of the tube or catheter is a small, sausage-shaped balloon. The balloon is inflated in the blocked artery, compressing the fatty build-up (atheroma) against the artery walls. The surgeon then deflates the balloon and removes it.
Another common type of angioplasty involves inserting a short stainless steel mesh tube, called a stent, at the same time as the balloon. As the balloon is deflated, the expanded stent is left in place to help keep the artery open.
This method helps to prevent the problem of reblockage (restenosis), which affects around a third of people following conventional balloon treatment.
Recently, doctors have begun to use stents that incorporate drugs to help prevent reblockage.
Doctors are also trying a number of newer ways to perform angioplasty. They're using devices to cut or drill out fatty deposits, vaporise them with a laser, or blast them with ultrasound.
But, as yet, these techniques haven't been proven to be better than the standard balloon or stent method. While they're being tested and developed in some centres in the UK, they're not routinely available.
Coronary bypass surgery
Coronary bypass surgery, medically known as coronary artery bypass graft or CABG (pronounced 'cabbage'), is an operation in which a blood vessel from another part of the body is grafted between the aorta (the main artery leading from the heart) and the coronary artery, or arteries, to bypass blockages and restore blood flow to the heart muscle.
A bypass can be done on each of the four coronary arteries if necessary, hence the terms single, double, triple or even quadruple graft, depending on how many arteries are bypassed. The operation can be done using conventional surgical techniques or by keyhole surgery (microsurgery).
While many people find this sort of surgery hugely improves their health, it's not without considerable risks.
CHD can frequently be controlled with drugs alone, but if the blood vessels have become severely narrowed, or if drug treatment is unable to control symptoms, surgery may be needed to open up or replace the blocked arteries.
Valve replacement
Diseased heart valves can be repaired or replaced with either mechanical valves or biological valves (made from human or animal tissue). Mechanical valves may last longer but usually require a person to take anticoagulant medicines because there is an increased risk of clots forming.
