- Coronary artery spasm (CAS) is a temporary discomfort or pain that is caused by a. temporary spasm (constriction) in one or more of your coronary arteries (the arteries. that supply oxygen and nutrients to your heart). It is sometimes called ‘Prinzmetal. angina’ and usually happens in people aged 50 years or younger.

Angina Angina pectoris, commonly known as angina, is the sensation of chest pain, pressure, or squeezing, often due to ischemia of the heart muscle from obstruction or spasm of the coronary arteries. typical presentation of stable angina is that of chest discomfort and associated symptoms precipitated by some activity (running, walking, etc.) with minimal or non-existent symptoms at rest or after administration of sublingual nitroglycerin.

- 1 Variant angina. 2  Variant angina, also called Prinzmetal's angina, is caused by a spasm in a coronary artery in which the artery temporarily narrows. 3  This narrowing reduces blood flow to your heart, causing chest pain. 4  Variant angina can occur even when you're at rest, and is often severe.

Your heart (coronary) arteries can become narrowed by deposits called plaques. This is called atherosclerosis. This reduced blood flow is a supply problem — your heart is not getting enough oxygen-rich blood.

- Ischemic cardiomyopathy (IC) is a condition that occurs when the heart muscle is weakened. In this condition, the left ventricle, which is the main heart muscle, is usually enlarged and dilated. This condition can be a result of a heart attack or coronary artery disease, a narrowing of the arteries.

Chest Pain 1 If your chest pain is due to coronary artery spasms, you may be prescribed drugs to control your discomfort. 2  These include nitrates, such as nitroglycerin, which work by increasing blood flow to the heart. 3  Nitrates also decrease the work of the heart by dilating (expanding) the arteries. 4  If you smoke, be sure to quit.

Cadaveric spasm This article needs attention from an expert in Biology. (August 2012) Cadaveric spasm, also known as postmortem spasm, instantaneous rigor, cataleptic rigidity, or instantaneous rigidity, is a rare form of muscular stiffening that occurs at the moment of death and persists into the period of rigor mortis.

- Coronary artery vasospasm, or smooth muscle constriction of the coronary artery, is an important cause of chest pain syndromes that can lead to myocardial infarction (MI), ventricular arrhythmias, and sudden death. It also plays a key role in the development of atherosclerotic lesions.

5 Things You Should Know About Coronary Spasm When chest pain isn’t from blocked arteries. Chest pain is a common symptom of coronary artery disease. However, people without fixed, severe coronary blockages also can have chest pain due to a rare condition called coronary spasm. While the number of people with coronary spasm is very small, the disorder is often misdiagnosed or not diagnosed at all.

Coronary Artery Spasm A coronary artery spasm is characterized by the tightening of muscles within the arteries of the heart. Blood can’t flow through these narrowed arteries and as a result, the heart receives less blood oxygen.t most, such patients may notice occasional light chest pain. The danger in this is that the contractions can eventually cause heart attacks. On the flip side, other patients may detect symptoms of a coronary artery spasm. Common symptoms may include: 1  chest pain (angina). 2  pain on the left side of your chest. 3  chest tightness.

- A. Dilated cardiomyopathy (DCM) is a condition in which the heart 's ability to pump blood is decreased because the heart's main pumping chamber, the left ventricle, is enlarged and weakened. In some cases, it prevents the heart from relaxing and filling with blood as it should.

Overview Angina is caused by reduced blood flow to your heart muscle. Your blood carries oxygen, which your heart muscle needs to survive. When your heart muscle isn't getting enough oxygen, it causes a condition called ischemia. The most common cause of reduced blood flow to your heart muscle is coronary artery disease (CAD). Your heart (coronary) arteries can become narrowed by deposits called plaques.

- Coronary Heart Disease is a condition which affects the vessels which supply the heart's muscle with blood, oxygen and nutrients. If these blood vessels (coronary arteries) become partially blocked, a person can have decreased heart function and may experience pain in the chest, arm, neck or jaw (angina).If the vessels become completely blocked, some of the heart muscle can die, which is called a heart attack (myocardial infarction).hat are the symptoms? The most common symptom of CHD is chest pain, but coronary heart disease can also be silent causing a heart attack or sudden death without any warning signs. The classic symptom of a heart attack is pain or pressure in the chest that can spread to the arm, shoulder, neck or jaw.

Cardiomyopathy In most cases of ischemia, this temporary blood shortage to the heart causes pain in the chest (called angina pectoris). In certain other cases, there is no pain (called silent ischemia). Ischemic cardiomyopathy is the loss or weakening of heart muscle tissue caused by ischemia or silent ischemia.

- Dilated cardiomyopathy. Dilated cardiomyopathy (DCM) is a condition in which the heart becomes enlarged and cannot pump blood efficiently. The decreased heart function can affect the lungs, liver, and other body systems. DCM is one of the cardiomyopathies, a group of diseases that affect primarily the heart muscle.

What Causes a Heart Attack? Coronary Artery Spasm. A less common cause of heart attack is a severe spasm (tightening) of a coronary artery. The spasm cuts off blood flow through the artery. Spasms can occur in coronary arteries that aren't affected by atherosclerosis. What causes a coronary artery to spasm isn't always clear.

Heart Attacks and Heart Disease This is a heart attack. While it is unusual, a heart attack can also be caused by a spasm of a coronary artery. During a coronary spasm, the coronary arteries restrict or spasm on and off, reducing blood supply to the heart muscle (ischemia). It may occur at rest, and can even occur in people without significant coronary artery disease.

How Much Do I Feed a Labrador Dog? July 19, 2011. 1  The amount you feed your pet Labrador will depend on the size, age and the amount of exercise the dog gets. While commercial dog food products have directions on the amount to feed, they are often too much and should only be used as a guideline after taking all the factors into consideration.

How could someone with relatively healthy arteries be at risk for a heart attack? In some instances, maybe one-third of cases, people with no major heart-attack risk factors can have a coronary artery spasm [source: ClevelandClinic ]. If it lasts, say, five minutes, the damage is minimal, limited to chest pain (or possibly no symptoms at all).

Medical Dictionary A muscle spasm can be quite painful, with the muscle clenching tightly. A spasm of the coronary artery can cause the pain of angina. Spasms in various types of tissue may be caused by stress, medication, and overexercise.

Coronary Microvascular Disease (MVD) Coronary heart disease (CHD), also called coronary artery disease, involves plaque formation that can block blood flow. In coronary MVD, the heart's tiny coronary artery blood vessels do not have plaque, but damage to the inner walls of the blood vessels that can lead to spasms and decrease blood flow to the heart muscle.

Raising Awareness for Early Signs of Heart Attack Acute coronary syndrome is an umbrella term used to describe conditions like heart attack and unstable chest pain, which occur when there’s a lack of blood flow to the heart. Many times, there are early cardiac symptoms in the days or week before a patient experiences this type of event.
