What is spontaneous coronary artery dissection?

What is spontaneous coronary artery dissection?

Overview. Spontaneous coronary artery dissection — sometimes referred to as SCAD — is an emergency condition that occurs when a tear forms in a blood vessel in the heart. SCAD can slow or block blood flow to the heart, causing a heart attack, heart rhythm problems (arrythmias) or sudden death.

What is non atherosclerotic coronary dissection?

Nonatherosclerotic spontaneous coronary artery dissection (NA-SCAD) is underdiagnosed and an important cause of myocardial infarction in young women. The frequency of predisposing and precipitating conditions and cardiovascular outcomes remains poorly described.

Does SCAD show up on an ECG?

The sooner a diagnosis is made, the better the outcome is likely to be. The longer blood flow is reduced, the higher the chance of permanent damage to heart muscles. Tests to diagnose heart attacks and SCAD include: ECG (electrocardiogram) – although ECGs can look normal in some SCAD patients.

Can SCAD heal on its own?

Whenever possible, health care providers allow the damaged artery to heal on its own. For some people, medications might relieve the symptoms of SCAD , so it might be possible to be treated with medications alone. If chest pain or other symptoms persist, other treatments might be needed.

What is the survival rate of SCAD?

Initial reviews of SCAD reported a mortality rate of 70% (11). More recently, the outcome of SCAD has been reported to be more favourable (6,12), with one review suggesting a survival rate of 82% (8).

Is SCAD classed as heart disease?

SCAD is difficult to diagnose before it causes a heart attack, because it doesn’t have any warning signs. And although it can cause a life-threatening heart attack, SCAD patients don’t typically have other heart disease risk factors.

What are the non-atherosclerotic causes for coronary artery disease?

SCAD, coronary artery embolism, coronary vasospasm, myocardial bridging and stress-induced cardiomyopathy (TTS) are notable causes of non-atherosclerotic ACS.

Can angina occur without coronary disease?

Several cardiac and medical conditions can cause angina even without atherosclerotic plaques that are producing discrete blockages in the coronary arteries. Some of these conditions actually do involve the coronary arteries, while others do not.

Can you live a normal life after SCAD?

SCAD can lead to abnormal heart rhythms, heart attack, or cardiac arrest. If SCAD is diagnosed quickly and treated properly, most people will have a full recovery. Patients will need regular follow-up appointments with their cardiologist to monitor their condition.

Can you have coronary artery disease without blockage?

Is this possible? A: Yes, this type of heart attack is called a myocardial infarction in the absence of obstructive coronary artery disease, or MINOCA. It accounts for 5 to 6% of heart attacks. Compared with other types of heart attacks, patients are usually younger and more likely to be female.

What is mild nonobstructive coronary disease?

Nonobstructive coronary artery disease (CAD) is atherosclerotic plaque that would not be expected to obstruct blood flow or result in anginal symptoms.

Can you have angina with no blockages?

Microvascular angina. This used to be called Syndrome X. It causes chest pain with no coronary artery blockage. The pain is caused by from poor function of tiny blood vessels that lead to the heart, arms, and legs. It is more common in women.

Why do I suddenly have angina?

Angina is caused by reduced blood flow to the heart muscle. Blood carries oxygen, which the heart muscle needs to survive. When the heart muscle isn’t getting enough oxygen, it causes a condition called ischemia. The most common cause of reduced blood flow to the heart muscle is coronary artery disease (CAD).

What SCAD feels like?

If you experience a SCAD episode you may have these symptoms: chest pain, pressure, tightness or heaviness. rapid heartbeat, fluttery feeling. pain in arms, shoulders, jaw, neck, back or stomach.

Can I exercise with SCAD?

Cardiac rehabilitation programs for patients with SCAD have shown physical and mental benefits. The authors recommend aerobic training for their patients with SCAD, including 30-40 minutes of moderate-intensity physical activity 5-7 days/week, similar to the general population.
