If diagnosed with cardiac ischemia, is it safe to exercise, or does physical activity worsen your condition?

Ischemia: You should discuss this with your cardiologist who may want to get a stress test before giving you specifics. ...Read more

Can cardiac ischemia cause arrhythmias? If so, how?

Can cardiac ischemia cause arrhythmias? If so, how?

Yes: Cardiac ischemia causes lack of blood flow to the heart muscle and can trigger ventricular arrhythmia. Premature ventricular contraction is common. In severe cases, it can also lead to ventricular tachycardia ( consecutive fast heart beat from the ventricle of the heart). Sometimes with heart attack, fatal ventricular fibrillation (very fast irregular abnormal beats from ventricle) can occur. ...Read more

Are cardiac ischemia and shortness of breath related?

Are cardiac ischemia and shortness of breath related?

Very possible: Shortness of breath often is a manifestation of cardiac ischemia. Although chest pain is a well known sign of cardiac ischemia , shortness of breath needs to be evaluated promptly. See your doctor. ...Read more

How reliable is an EKG as a predictive tool for cardiac ischemia?

How reliable is an EKG as a predictive tool for cardiac ischemia?

Poor: It is neither sensitive nor highly specific. It's only one tool among many that doctors use. It's helpful for confirming a clinical suspicion if the history is suggestive and the ekg is either dramatically abnormal or changed from a previous tracing. Its value is increased when performed during the index symptom under evaluation. ...Read more

What is the relationship between cardiac ischemia and shortness of breath?

Symptoms: Cardiac ischemia (lack of enough blood supply to a part of the heart muscle) can manifest as shorteness of breath (second most common symptom after chest pain). ...Read more

Can you tell me the difference between cardiac ischemia and coronary heart disease?

Can you tell me the difference between cardiac ischemia and coronary heart disease?

Overlap: Cardiac ischemia can be the result of coronary artery disease, cad, the latter being a progressive disease that can result in plaque/cholesterol building up in the coronary arteries and these stenoses or blockages can impair blood flow to the heart.Ischemia is the condition of blood flow and so oxygen being kept from a part of the body; cardiac ischemia is when this deprivation occurs in heart. ...Read more

I diagnosed of interior wall ischemia is this dangerous to be anger or fear? If that emotion comes always is this a high risk of cardiac arrest?

I diagnosed of interior wall ischemia is this dangerous to be anger or fear?  If that emotion comes always is this a high risk of cardiac arrest?

Ischemia: Ischemia means a narrowing of the arteries that feed the heart muscle. Any type of stress, either physical exertion or mental stress can strain the heart. This could disrupt a cholesterol plaque and cause a heart attack which in some cases result in cardiac arrest. It is not possible to directly assess if this is high risk, but people with ischemia are at higher risk than normal population. ...Read more

What is the significance of coronary ischemia?

What is the significance of coronary ischemia?

Blood flow limited: It means that the heart muscle is not getting enough blood flow to meet its metabolic demands to carry out the required activities. This usually connotes a narrowing ("blockage") in one of the major coronary arteries that supplies heart muscle with blood, and hence oxygen. ...Read more

How does the body change to try to compensate for coronary ischemia?

How does the body change to try to compensate for coronary ischemia?

Coronary ischemia: The body will try to limit activity in order to decrease ischemia, so some people will feel fatigue or shortness of breath. Also often people have angina or chest pain with activity which limits activity. On the local level small vessels called collateral vessels can grow to bypass the blockage. ...Read more

How does the body try to compensate for coronary ischemia by growing new vessels?

How does the body try to compensate for coronary ischemia by growing new vessels?

Good question: Through biochemical mechanisms stimulated by decreased blood flow to areas of the heart, small collateral arteries can form as branches of the larger coronary arteries in order to maintain as much blood supply to the heart as possible. These collateral arteries can often prevent permanent damage to the heart, but they rarely normalize the blood flow necessary for normal heart function. ...Read more

Coronary ischemia effects? Do a few heart muscle cells die each time you have angina?

Coronary ischemia effects? Do a few heart muscle cells die each time you have angina?

Not necessarily: Angina is a symptom of chest discomfort. Heart cells die only when the blood supply to the heart is stopped for at least 20 minutes. Angina may occur with no stoppage of blood to the heart, or it may occur in the presence of a damaging heart attack, known as myocardial infarction. ...Read more

How does coronary artery disease lead to myocardial ischemia?

How does coronary artery disease lead to myocardial ischemia?

By blocking the flow: In young, healthy individuals the inner lining of the blood vessels is clean and smooth. Overtime, for many reasons, the inner surface of the heart blood vessels (coronary arteries) may start becoming bumpy/lumpy or blocked due to fat (cholesterol) deposits called "atherosclerotic plaque". This in turn reduces the amount of blood flow available causing "ischemia" (oxygen deprivation). ...Read more

With congestive heart failure or coronary ischemia would the oxygen saturation shown on the monitor at hospitals drop?

With congestive heart failure or coronary ischemia would the oxygen saturation shown on the monitor at hospitals drop?

Possibly: With severe or "decompensated" congestive heart failure, the oxygen saturation is frequently low due to the pint of water in the lungs. As this condition is treated, the oxygen level will improve. For ischemia, it would be very unc. ...Read more

Hi, What is Cardiac Ischaemia and can it cause Pulmonary Embolism. Many thanks.

Hi, What is Cardiac Ischaemia and can it cause Pulmonary Embolism. Many thanks.

Cardiac ischaemia.: Cardiac ischemia denotes a reduction in blood flow through the arteries that supply the heart with blood. This would typically happen in the context of blockages within the arteries of the heart. This does not directly cause pulmonary emboli. ...Read more
