What Is Coronary Artery Disease
Most heart attacks are caused by coronary artery disease . This is when a gradual build-up of fatty streaks form in the coronary arteries. These are the arteries that deliver oxygenated blood to the heart muscle. The build-up of fatty streaks makes the coronary arteries narrow and stiffen over time.
As the coronary arteries narrow, it becomes more difficult for oxygenated blood to reach the heart muscle, sometimes causing pain and discomfort known as angina.
If a piece of plaque cracks, it may cause a blood clot to form and block a coronary artery, cutting off the blood supply to a part of the heart muscle. This causes a heart attack.
The heart attack symptoms you feel during a heart attack are caused by your heart muscle being starved of oxygen. This prevents your heart from beating as normal.
Similarities Differences And Links Between Afib And Anxiety Attacks
So many common symptoms of atrial fibrillation resemble classic anxiety symptoms that characterize panic attacks: heart palpitations, chest pain, muscle tension, and sweaty palms that come with an adrenaline rush are good examples.
Luckily, these symptoms are generally short-lived, whether its an AFib episode or a panic attack. However, in order to treat your body properly and sidestep potential complications down the road, its important to distinguish the two conditions.
Myth: If My Heart Rate Is Normal My Blood Pressure Is Fine
Sometimes your heart rate and your blood pressure go hand in hand. For example, when you exercise, or get angry or scared, they both go up.
But theyre not always linked. If your heart rate is normal, your blood pressure may not be. It could be too high or too low, and you may not realize it.
Even if your heart rate seems fine, get your blood pressure checked regularly.
In some people, there may be little change to your blood pressure at all. In other cases, there may be an increase in blood pressure. Any blood pressure changes that may occur during a heart attack are unpredictable, so doctors generally dont use them as a sign of a heart attack.

What Causes Sudden Cardiac Arrest
Your heart has an electrical system that controls the rate and rhythm of your heartbeat. An SCA can happen when the heart’s electrical system is not working right and causes irregular heartbeats. Irregular heartbeats are called arrhythmias. There are different types. They may cause the heart to beat too fast, too slow, or with an irregular rhythm. Some can cause the heart to stop pumping blood to the body this is the type that causes SCA.
Certain diseases and conditions can cause the electrical problems that lead to SCA. They include
- Ventricular fibrillation, a type of arrhythmia where the ventricles don’t beat normally. Instead, they beat very fast and very irregularly. They can’t pump blood to the body. This causes most SCAs.
- Coronary artery disease , also called ischemic heart disease. CAD happens when the arteries of the heart cannot deliver enough oxygen-rich blood to the heart. It is often caused by the buildup of plaque, a waxy substance, inside the lining of larger coronary arteries. The plaque blocks some or all of the blood flow to the heart.
- Some types of physical stress can cause your heart’s electrical system to fail, such as
- Intense physical activity in which your body releases the hormone adrenaline. This hormone can trigger SCA in people who have heart problems.
- Very low blood levels of potassium or magnesium. These minerals play an important role in your heart’s electrical system.
- Major blood loss
- Severe lack of oxygen
Find The Right Activity For You
There are no bad activities for people with asthma. And you dont have to sign up for a marathon taking a daily walk, playing more vigorously with your kids or grandchildren, or doing some gardening all count.
Even just sitting down a little less during your day has major health benefits.
People with asthma tell us they enjoy:
- Walking, especially with a walking group, because of the other benefits like being outside and meeting people
- Yoga and tai chi because they let you set the pace and relax, as well as helping with breathing control
- Some people with asthma say swimming really helps, but others report that the chlorine makes their symptoms flare up
- NHS programmes like Couch to 5K and Strength and Flex are free, can be done at home, and are designed for absolute beginners
- Walking netball or chair yoga are great for building up your confidence there are lots of other modified sports you could try search for inclusive sports groups in your area
What has helped me is to learn exercise can be done in one minute blocks and incorporated into my daily life. Asthma UK Readers Panel member

Why Your Heart Races
Panic attacks occur when you feel triggered by something in your environment. Many experience this trigger on an unconscious level, and it is difficult to identify. Think about the last time you felt startled. Panic attacks are similar in that the mind and body experience a fear response. Your heart also races because:
- Your body initiates fight, flight, or flee response.
- Your body releases adrenaline, also known as epinephrine. It gives surge of energy to act quickly and make fast decisions.
- Your heart pumps blood at a faster rate towards your muscles, which would help you flee if necessary.
Literature Search And Study Characteristics
After exclusion of nonrelevant and duplicate articles, 523 records were reviewed in full. Another 478 records were excluded for other reasons , and 45 prospective cohort studies were included in this meta-analysis. Of the 45 studies , 30 provided results for coronary artery disease , 17 provided results for stroke , 12 provided results for noncardiovascular diseases , 10 provided results for all types of cancer , 7 provided results for noncardiovascular diseases excluding cancer , and 7 provided results for sudden death . The follow-up duration ranged from 2 to 40 years. The study quality ranged from 5 to 9 stars . Detailed information about the included studies appears in Appendix 4 .

How Is A Heart Attack Treated
Quick treatment to get the blood flowing to your heart muscle again is important. This can reduce the amount of permanent damage to your heart and save your life.
Many people need to have emergency treatment to restore the blood flow:
- Coronary angioplasty re-opens the blocked coronary artery by inserting one or more stents. This helps keep the narrowed artery open.
- Thrombolysis involves giving you clot-busting medicine to dissolve the blood clot that’s blocking the coronary artery.
- Coronary bypass surgery helps to restore normal blood flow by using a blood vessel from your leg, arm or chest in your heart to bypass the blocked artery.
You might not have these treatments if your doctor decides it’s not safe or necessary.
How Many Times A Heart Beats Per Minute Before You Have A Heart Attack
A heart attack occurs as a result of the sudden blockage in the arteries of heart that supply blood to the heart. The location and amount of blockage decide the fate of heart attack. Normally heart beats at the rate of 60 to 80 beats per minute. Disruption of blood flow in the arteries of the heart due to blockage is a heart attack. The heart rate when you have a heart attack may alter and can be either slower or faster than normal heart rate or maybe with skipped beats or extra abnormal beats.

Can You Have A Normal Pulse During A Heart Attack
A normal heart rate is 60-80 beats per minute, but during a heart attack that rate is altered due to the disrupted blood flow. Heart rates during a heart attack can vary from too slow or fast to palpitations and even skipped beats. Where the blockage in the heart occurs often has a direct correlation on the type of heart rate.

How Do I Avoid A 2nd Heart Attack
To avoid a recurrence, possibly resulting in death, pay attention right away to treatment and prevention measures, said Dr. Nieca Goldberg, medical director for the Joan H. Tisch Center for Women’s Health at New York University’s Langone Medical Center. “Really be proactive.”
The right actions can also help you return to regular activities more quickly, set a course for a healthier future, and help lower the risk of a second heart attack.
Returning Heart Rate To Normal
Many people can eventually learn how to ground themselves during an attack, or right before they experience another. If youve had more than one panic attack, think about what happens right before your symptoms show up. If you are able to identify when you are about to have a panic attack, it will be easier for you to get yourself back to a calmer state instead of trying to do so during the attack. Here are a few exercises to try before, during or after a panic attack has occurred:
- Progressive muscle relaxation: This provides an easy to learn exercise that helps you get connected to your body
- Guided imagery relaxation exercise: This an audio exercise where an instructor helps lead you to a more peaceful state of mind.
- Deep breathing exercises: These offer a quick way to relax and slow down your heart rate.
If you see a doctor, he or she may also prescribe:
- SSRIs: These are otherwise known as selective serotonin reuptake inhibitors, and they are used to treat anxiety based disorders, as well as depressive disorders.
- SNRIs: Also known as selective norepinephrine reuptake inhibitors, these meds are used to treat anxiety and depressive disorders.
- Benzodiazepines: These are sedatives and can typically induce a calming effect within 15 to 30 minutes.

Resting Heart Rate Can Predict Heart Attacks In Women
Research: Resting heart rate as a low-tech predictor of coronary events in women
A simple measurement of resting pulse predicts coronary events in women independently of physical activity and common risk factors, such as smoking and alcohol consumption, finds a study published on bmj.com today.
Previous studies have shown that resting heart rate predicts coronary events in men. But, for women, the relationship between heart rate and coronary events or stroke remains uncertain.
So researchers in the USA assessed resting heart rate in 129,135 postmenopausal women with no history of heart problems. Risk factors that might be expected to affect heart rate, such as high blood pressure, high cholesterol levels, smoking and alcohol intake were taken into account at the start of the study. The women were monitored for an average of 7.8 years, during which time all hospital stays and coronary events were recorded.
During the study period, 2,281 coronary events and 1,877 strokes occurred.
Women with the highest resting heart rate were significantly more likely to suffer a coronary event than women with the lowest resting heart rate .
Further analysis showed that this association was independent of physical activity, did not differ between white and minority women, or those with or without diabetes, but was stronger in women 50-64 years of age than among women 65 years or older.
There was no such relationship between resting heart rate and stroke.

Does heart rate increase with inspiration?
The heart rate increases during inspiration and decreases during the post-inspiration/expiration period. This respiratory-related change in heart rate, respiratory sinus arrhythmia , helps to match pulmonary blood flow to lung inflation and to maintain an appropriate diffusion gradient for oxygen in the lungs.

Chest Pain That Isnt Caused By A Heart Attack
You feel a pain in your chest and left arm. You immediately start worrying that you’re having a heart attack. At what point do chest pains equal a heart attack? Emergency room physician Dr. Troy Madsen shares what chest pains can mean. He also discusses the symptoms and feelings of a heart attack versus “regular” chest pain.
Signs Of Heart Attack That You Shouldnt Ignore
About every 40 seconds, someone has a heart attack in the US. Most people imagine that having a heart attack is always intense. But the truth is that sometimes you may be unsure if your are suffering from a heart attack because the signs can be subtle and different from what you may typically think of.
This makes heart attacks very dangerous. In fact, 1 in 5 heart attacks goes unnoticed, meaning the heart muscle is damaged due to lack of blood supply but the person is not aware of that this has occurred.
So what are the signs of a heart attack both subtle and not-so-subtle? Here are 4 signs of heart attack to be on the lookout for:

Arm Back Neck Jaw Or Stomach Pain Or Discomfort
Heart attack pain may not be confined to the chest area. Pain or discomfort in your arm, back, neck, jaw, or stomach can also be heart attack-related.
But many people do not associate pain in these areas with having a heart attack which may prevent them from getting immediate medical attention.
Some head-to-toe signs of a heart attack include:
- Jaw, neck, or back pain
- Arm or shoulder pain or discomfort
- Shortness of breath
If you feel sudden discomfort in these areas, call 9-1-1.
How Can Asthma Be Managed
You have to realise that a large part of managing your asthma is going to be your responsibility. Your doctor will explain to you the nature of asthma and how to deal with asthma. You or your childs asthma and lung function will also need monitoring regularly, either by peak flow or by spirometry. Peak flow measurements are quick and easy to do, and you can do it at home. Spirometry might require you to see your doctor.
It is important that you avoid any factors that make your symptoms worse. This might involve avoiding animals or pets, or avoiding dusty places or places with lots of air pollution. Asthma can be triggered by a mould or house dust mite allergy as well both of these organisms can be removed by reducing the humidity of your house and cleaning regularly. If your child suffers from asthma when he or she is doing exercise, you might need to explain this to school so they can have special provisions made. Avoiding the cold weather is difficult wear lots of layers during the cold months. Central heating can encourage growth of moulds and house dust mite colonies, so this might not be a great idea if you or your child has a mould allergy or a house dust mite allergy.
There are also medications available to help you out. Inhalers are given out by prescription by your doctor.

Can Sudden Cardiac Arrest Be Prevented
You may be able to lower your risk of SCA by following a heart-healthy lifestyle. If you have coronary artery disease or another heart disease, treating that disease can also lower your risk of SCA. If you have had an SCA, getting an implantable cardioverter defibrillator can lower your chance of having another SCA.

Signs Symptoms And Risk Factors For Cardiac Arrest
Many people believe that cardiac arrest causes the heart to stop beating immediately. While its true that some areas of cardiac muscle will start to die during a heart attack because of a lack of blood, a persons pulse may become slower or faster , depending on the type of heart attack theyre experiencing .
Other signs and symptoms of heart attack include a sudden onset of:
- Pain, pressure, or tightness in the chest
- Arm, neck, back, or jaw pain
- A feeling of “impending doom”
- Shortness of breath
- A sudden cold sweat
Both men and women experience heart attacks. Specific risk factors for cardiac arrest include smoking, chronic inflammation, obesity, high blood pressure, physical inactivity, and family history.

Symptoms Of Heart Disease
With menopause, factors conspire to change a womans risk for heart disease, Foody says. Its important for women to understand that while menopause transition is natural, some of the symptoms associated with it, such as heart palpitations or increases in blood pressure, can have significant consequences.
Women should check with their doctor to be sure what theyre experiencing is still within a range of normal, Foody notes.
Symptoms you should never ignore include:
1. Palpitations Dont assume heart palpitations are natural flutters, says Rosen. Its important to identify atrial fibrillation, because this heart condition increases the risk of stroke, adds Foody.
2. Shortness of breath If you were able to go up the stairs fine, and now you find you are short of breath, talk to your healthcare provider, says Foody. It could be a sign of congestive heart failure or coronary artery disease. Shortness of breath is also one of the most common symptoms of atrial fibrillation.
3. Pressure in the chest It could be an indication of heart disease. Some women think that unless they have crushing chest pain, its not a heart attack, Foody reports. A feeling of fullness, squeezing or dull pressure in the chest that doesnt go away or that goes away and comes back could be a sign of a heart attack in women.
4. Headaches They might be a sign of high blood pressure, so get any symptoms checked out.
