Hello frnds.....today v learn about heart attack...their symptoms...diagnosis ...nd treatment...so let's start nd read this article carefully....

What is heart attack?

Heart attack is the death of a segment of heart muscle caused by the loss of blood supply.

The blood supply is usually lost because a coronary artery, one that supplies blood to the heart muscle, is blocked by a blood clot (coronary thrombosis).

If some of the heart muscle dies, the patient experiences chest pain and electrical instability of the heart muscle tissue.

This article will cover information about how and why heart attacks occur, how they are treated, and how to prevent them.

Symptoms

The following are signs and symptoms for diagnosing a heart attack:

Chest discomfort, mild pain

Coughing

Nausea

Vomiting

Crushing chest pain

Pressure tightness, pain, squeezing or aching in the chest or arms that spreads to the neck, jaw, or back

Dizziness

Dyspnea (shortness of breath)

Face seems gray

A feeling of terror that your life is coming to its end

Feeling really awful (general feeling)

Restlessness

Feeling clammy and sweaty

Shortness of breath

Causes

The following are possible factors associated with increased risk of heart attack.

Age: Risk increases when a man is over 45, and a woman is over 55.

Angina: An illness where not enough oxygen reaches the heart, causing chest pain resembling a heart attack, but it resolves after taking medication. Angina raises the risk of a heart attack.

High blood cholesterol levels: Increases the risk of developing blood clots in the arteries.

Diabetes: People with diabetes have a higher risk of developing several diseases and conditions, many of them contribute to a higher risk of heart attack.

Diet: Someone who consumes large quantities of, for example, saturated fats, will eventually have a higher risk of having a heart attack.

Genes: You can inherit a higher risk of heart attack.

Heart surgery: Patients who have had heart surgery have a higher risk.

Hypertension (high blood pressure).

Obesity, overweight.

Physical inactivity: More active people have a lower risk.

Previous heart attack: Anybody who has already had a heart attack is more likely to have another one, compared with people who have not.

Smoking.

HIV: People who are HIV positive have a 50 percent higher risk of heart attack.

Work stress: Individuals with stressful jobs, or shift workers have an increased risk of heart attack.

Diagnosis

ECG (Electrocardiograph): Monitors the electrical activity of the heart muscles

Cardiac enzyme tests: Blood tests detect enzymes produced during a heart attack

Chest X-ray: To look for swelling of the heart.

Treatment

Manual chest compressions - continuous chest compressions to the heart at about 100 beats per minute.

Defibrillator - the defibrillator sends electric shocks across the patient's chest - the aim is to use electricity to shock the heart back into proper activity.

Aspirin - often given to patients during a heart attack. Aspirin will help stop the clot in the artery from growing.

Thrombolytics - these dissolve blood clots.

Painkillers - morphine is sometimes injected into the patient to control the pain and reduce anxiety.
