High Blood Pressure And Heart Attack

Don't Miss

Patients Who Present In The Emergency Room With Chest Pain Are Given A Troponin Test

High blood pressure can lead to a heart attack

Troponin is a protein enzyme that leaks from the heart when this muscle is damaged.

If the test result is elevated , this can mean that the patient had a heart attack very recently.

However, elevated troponin doesnt always mean cardiac damage.

In fact, the test result isnt either normal or elevated there is another range an in-between range.

Its sometimes referred to as a gray area or indeterminate area, which warrants a follow-up blood draw several hours later to see if the result is of a higher value .

Being Overweight And Cardiovascular Disease Risk

Being overweight or obese increases your risk of a number of health problems, including:

Carrying extra weight around your middle is more of a health risk, so it is especially important for you to lose weight if this is the case.

To achieve a healthy body weight, balance the energy coming into your body through food and drinks, with the energy being used up by your body through regular physical activity.

High Blood Pressure Can Cause A Heart Attack It Makes Your Heart Work Harder And Could Lead To A Buildup Of Cholesterol And Plaque In Your Arteries Increasing The Risk Of Heart Attacks And Stroke

Story by: Norton Healthcare on January 25, 2019

High blood pressure puts extra strain on the heart and arteries. Years of untreated high blood pressure and the strain it puts on artery walls creates places for cholesterol to build up and form hardened patches of plaque.

If the plaque ruptures, bits and pieces enter the bloodstream, where they can form blood clots.

High blood pressure rarely shows symptoms. Checking your numbers regularly is critical to avoiding long-term complications such as heart disease, congestive heart failure, stroke, impaired vision and kidney disease.

Life-threatening conditions caused by high blood pressure include:

  • Heart attack: Over time, high blood pressure can damage the lining of your arteries. Fats in your bloodstream can collect along the damaged walls. Cholesterol and triglycerides combine to form plaque and cause atherosclerosis hardening and narrowing of the arteries. If the plaque breaks loose and causes a blood clots in the heart, thats a heart attack.
  • Stroke: If the buildup sends clots into the brain, the result is a stroke.
  • Heart failure: The extra workload on the heart can lead to an enlarged heart. That makes it harder for your heart to meet your bodys need for oxygen and nutrients.

Risk Factors For A Silent Heart Attack In Women

Still, Ekery says, the risk factors for a silent heart attack are the same as those for a recognized heart attack, and:

A silent heart attack can be just as dangerous as its more obvious counterpart, says Ekery. Because the event often leaves scarring and damage to the heart, it puts the person at greater risk of other heart problems. And because the person didnt know to seek treatment, blood flow to the heart might not have been restored early on, and no medications were administered, so the impact could potentially be greater.

A Simple And Highly Sensitive Blood Test Can Detect If You Just Suffered A Heart Attackand This Test Is So Super Sensitive That It Can Detect Even A Mild Heart Attack

Is High Blood Pressure A Symptom Of Heart Attack

The blood test is for an enzymatic protein called troponin. The troponin blood test for heart attack is highly sensitive and is considered the gold standard for determining damage to cardiac muscle.

Cardiac enzymes are chemicals contained within heart cells, says Christopher J. Hanifin, PA-C, who was previously a physician assistant in open heart surgery with Cardiothoracic Surgery of South Bend in South Bend, IN.

Normally, they are essentially undetectable in the bloodstream, continues Hanifin.

When a person suffers a heart attack, cells in the heart die and rupture, releasing these enzymes into the blood where they can be detected.

Diagnosis of a heart attack is usually based upon the detection of elevated levels of these chemicals in the blood.

If you go into an emergency room complaining of current or recent chest pain, the doctor or physician assistant will order a blood draw to check your troponin levels.

So if a patient goes to the emergency department with chest pain and their cardiac enzymes tests are negative, are they in the clear? Not necessarily, says Hanifin.

It takes some time for cardiac enzymes to appear in the blood. If a patient is tested in the early stages of a heart attack, it is very possible that their levels will be within normal ranges.

However, an elevated troponin level alone should not be used to outright diagnose heart attack.

Its never elevated by accident. As mentioned, this blood test is super sensitive.

What Happens During A Heart Attack

A heart attack happens when blood flow to a section of the heart becomes blocked. Heart attacks are different for everyone. Some are sudden and intense and sometimes accompanied by chest pain. Most heart attacks, however, start slowly with mild pain and discomfort. Symptoms can vary among men and women.

What If Lifestyle Changes Dont Help Lower My Blood Pressure

If diet, exercise and other lifestyle changes dont work to lower your blood pressure, your healthcare provider will prescribe medications to help lower your blood pressure. Your provider will take into account other conditions you may have, such as heart or kidney disease and other drugs youre taking when prescribing medications to treat your high blood pressure. Be sure to follow your providers dosing directions exactly.

Blood Pressure And Cardiovascular Disease Risk

Blood pressure is the pressure of the blood in your arteries as it is pumped around your body by your heart. Blood pressure depends on two main things: the amount of blood pumped by your heart and how easily the blood can flow through your arteries.

Your blood pressure will go up and down throughout the day, depending on the time of day and what you are doing. However, high blood pressure is a condition where your blood pressure is consistently high.

Your family history, eating patterns, alcohol intake, weight and level of physical activity have a strong influence on blood pressure. In some people, medicines, including the oral contraceptive pill, contraceptive âdepotâ injections, steroids and arthritis medicines, can also raise blood pressure.

High blood pressure can overload your heart and arteries and speed up the artery-clogging process. This can lead to problems such as heart attack and stroke.

High blood pressure can also affect arteries to other parts of your body, such as the eyes, kidneys and legs.

If high blood pressure is not treated, your heart may weaken because of the constant extra demand. This may cause âheart failureâ, a serious condition with symptoms such as tiredness, shortness of breath and swelling of the feet and ankles.

Chest Pain Pressure Squeezing And Fullness

Picture someone having a heart attack, and chances are you imagine them gasping for air and clutching their chest before falling unconscious. While you may experience chest pain during a heart attack, it may not be as dramatic. In some cases, it may not even be described as pain. Instead, it may feel more like pressure or squeezing in the chest.

Chest pain or chest discomfort is caused by an insufficient supply of oxygen-rich blood to your heart. During a heart attack, you may feel this pain in the center of the chest. It can last for a few minutes and disappear, or it may recur after a short break.

This symptom is a warning sign of blocked or narrowed arteries. Dont hesitate to report this to your doctor, even if this and other symptoms are not intense.

What Can I Expect If I Have This Condition

Since high blood pressure doesnt cause many symptoms at first, you probably wont feel any different with a high blood pressure diagnosis. But its important to follow your providers instructions to bring your blood pressure down so it doesnt cause serious illnesses later in life.

How long does high blood pressure last?

If you have primary high blood pressure, youll need to control it for the rest of your life.

If you have secondary high blood pressure, your blood pressure will most likely come down after you receive treatment for the medical problem that caused it. If a medication caused your high blood pressure, switching to a different medicine may lower your blood pressure.

What is the outlook for high blood pressure?

You can get seriously ill if you dont treat your high blood pressure. However, if you take the medicines your provider ordered, you can control your blood pressure. Exercising and eating healthy foods also helps lower your blood pressure.

Risk Of A Repeat Heart Attack

Essential or Primary Hypertension high blood pressure sphygmomanometer ...

Once youve had a heart attack, youre at higher risk for another one. Knowing the difference between angina and a heart attack is important. Angina is chest pain that occurs in people who have ischemic heart disease.

The pain from angina usually occurs after physical exertion and goes away in a few minutes when you rest or take medicine as directed.

The pain from a heart attack usually is more severe than the pain from angina. Heart attack pain doesnt go away when you rest or take medicine.

If you dont know whether your chest pain is angina or a heart attack, call 911.

The symptoms of a second heart attack may not be the same as those of a first heart attack. Dont take a chance if youre in doubt. Always call 911 right away if you or someone else has heart attack symptoms.

Unfortunately, most heart attack victims wait 2 hours or more after their symptoms start before they seek medical help. This delay can result in lasting heart damage or death.

Heart Attack And Heart Disease

High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause:

  • Chest pain, also called angina.
  • Heart attack, which happens when the blood supply to your heart is blocked and heart muscle begins to die without enough oxygen. The longer the blood flow is blocked, the greater the damage to the heart.
  • Heart failure, a condition that means your heart cant pump enough blood and oxygen to your other organs.

A Lot Of Diagnoses A Lot Of Misunderstanding

Managing High Blood Pressure After a Heart Attack

A June 2020 paper in the Journal of Atrial Fibrillation , describes the lesser-known diagnoses of a racing heart and the problem of heart rate messaging miscommunication in the autonomic nervous system.

The cardiovascular branch of the autonomic nervous system is responsible for the regulation of heart rate, blood pressure, and maintaining homeostasis during physiological stress such as exercise and standing upright. The autonomic nervous system constantly controls the rate and force of heart contractions and the vascular tone with the aim to maintain the sufficient tissue perfusion with oxygenated blood and secure venous return to the heart. .

  • Dysautonomia problems of or dysfunction of the autonomic nervous system.

Dysautonomias, the result of an autonomic nervous system malfunction, is often found in patients with cardiovascular symptoms. Apart from the most prevalent one, arterial hypertension , the cardiovascular dysautonomic continuum encompasses other important although less known conditions: postural orthostatic tachycardia syndrome, inappropriate sinus tachycardia, orthostatic hypotension and reflex syncope . Moreover, heart diseases may evoke autonomic imbalance by themselves cardiac pump failure is usually associated with sympathetic hyperactivity , neuroendocrine vasopressor activation , higher heart rate, reduced heart rate variability and baroreflex hyposensitivity , all of which are predictors of adverse outcomes.

Blood Pressure Is Typically Recorded As Two Numbers And A Written As A Ratio

  • Systolic: The top number in the ratio, which is also the higher of the two, measures the pressure in the arteries when the heart beats.
  • Diastolic: The bottom number in the ratio, which is also the lower of the two, measures the pressure in the arteries between heartbeats.

Your blood pressure rises with each heartbeat and falls when your heart relaxes between beats. While it can change from minute to minute with changes in posture, exercise, stress or sleep, it should normally be less than 120/80 mm Hg for women or men aged 20 or over.

What You Can Do Now To Prevent An Early Heart Attack
