A heart attack is a frightening experience. If you have experienced a heart attack, or are close with someone who has, are probably still reeling from the experience. But tens of thousands of people survive heart attacks and go on to lead productive, enjoyable lives. Some of the frequently asked questions below can help you better understand what has happened, and how your heart can heal. Knowledge is power. Arming yourself with this information can help you can live a healthier, longer life. Let us look at some of the facts:
Your heart muscle needs oxygen to survive. A heart attack occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or cut off completely. This happens because coronary arteries that supply the heart muscle with blood flow can become narrowed from a buildup of fat, cholesterol and other substances that together are called plaque.
This slow process is known as atherosclerosis and is discussed below. When plaque within a heart artery breaks, a blood clot forms around the plaque. This blood clot can block the blood flow through the artery to the heart muscle.
Ischemia results when the heart muscle is starved for oxygen and nutrients. When damage or death of part of the heart muscle occurs as a result of ischemia, it’s called a heart attack, or myocardial infarction (MI).
The vast majority of heart attacks occur because of a blockage in one of the blood vessels that supply your heart. This most often happens because of plaque, a sticky substance that can build up on the insides of your arteries (similar to how pouring grease down your kitchen sink can clog your home plumbing). That buildup is called atherosclerosis. Sometimes, plaque deposits inside the coronary (heart) arteries can break open or rupture, and a blood clot can get stuck where the rupture happened. If the clot blocks the artery, this can deprive the heart muscle of blood and cause a heart attack.
Heart attacks are possible without a blockage, but this is rare and only accounts for about 5% of all heart attacks. This kind of heart attack can occur for the following reasons:
Some heart attacks strike suddenly. But many people have warning signs and symptoms hours, days or weeks in advance. Chest pain or pressure (angina) that keeps happening and doesn't go away with rest may be an early warning sign.
The major symptoms of a heart attack are
Other symptoms of a heart attack could include unusual or unexplained tiredness and nausea or vomiting.
Higher levels of estrogen can reduce the risk of a heart attack. As a result, women have a greater risk of a heart attack after menopause than before menopause. However, women who have a heart attack are more at risk of underdiagnosis and undertreatment.
Although some women have no symptoms, others may have:
Our specialist team of cardiologists typically diagnose a heart attack after they perform a physical exam and review your medical history. They will likely conduct an electrocardiogram (ECG) to check your heart’s electrical activity.
An echocardiogram, which uses sound waves to create an image of the heart’s chambers and valves, can reveal how blood is flowing through the heart and what parts of the heart, if any, have been damaged.
They may also order a cardiac catheterization. This is a probe inserted into the blood vessels through a flexible tube called a catheter. It allows your doctor to view areas in and around your heart where plaque may have built up. They can also inject dye into your arteries, order an X-ray to see how the blood flows, and view any blockages.
Another step could include taking a sample of your blood or perform other tests to see if there’s evidence of heart muscle damage.
A commonly used blood test checks for levels of troponin T, a protein found in the heart muscle. Elevated levels of troponin T in the bloodstream is associated with a heart attack.
Heart attacks can result in various complications. When a heart attack occurs, it can disrupt your heart’s normal rhythm, potentially stopping it altogether. These abnormal rhythms are known as arrhythmias.
When your heart stops getting a supply of blood during a heart attack, some of the heart tissue can die. This can weaken your heart and cause serious complications such as heart failure.
Heart attacks can also affect your heart valves and cause leaks.
The long-term effects on your heart will be determined by how much time it takes to receive medical treatment and how much of your heart has been damaged from the heart attack.
A heart attack can damage your heart muscles and impact their function. This can include changing your heart’s rhythm and reducing its ability to pump blood effectively to all the organs and tissues in your body.
Following a heart attack, it’s important to work with your healthcare team to design a recovery plan. This plan may include the following lifestyle changes:

الملايين من الناس يأخذون الفيتامينات المتعددة كل يوم. يعتقد البعض أنه نوع من التأمين في حالة فقدان نظامهم الغذائي لبعض العناصر الغذائية الأساسية. يعتقد البعض الآخر أنه يقي من المرض عن طريق تعزيز المناعة ، أو تحسين صحة الدماغ ، أو تنظيم التمثيل الغذائي. من السهل معرفة مصدر هذه الأفكار: تروج الإعلانات لفوائد صحية واسعة النطاق ، على الرغم من أن معظمها يقدم القليل من الأدلة أو لا يقدم أي دليل لدعم الادعاءات.
Influenza, commonly known as the flu, is an extremely contagious respiratory illness caused by Influenza A or B viruses that infect the nose, throat, and sometimes the lungs. Flu appears most frequently in winter and early spring. It can range from mild to severe. When ill with the flu, people often feel some (or even all) of these flu symptoms:
You wake up tired, but you know that you’ve got something to look forward to. It’s not your morning commute, your day at work or getting the kids to school on time.
It’s your morning cup of coffee. You’re not alone.
Is drinking coffee bad for you?
Some people say their heart feels weird after drinking coffee. They may experience a racing heart, heart palpitations or an increased heart rate. So, does that mean coffee is bad for the heart?
Science has the answer to these questions, and for coffee drinkers, there’s some good news and some bad news.
