Question 1

how much blockage in artery or arteries can cause a heart attack.  also does blockage come from plaque and clot.

Accepted Answer

Blockage is 100%: to suffer an injury the artery must get closed off for a period of time. Talks about percent stenosis (narrowing) reflect how much of the native artery remains open for flow, that number also gives an estimate about how possible it would be for a small clot to come along and plug up that vessel. The usual way the "door slams shut" is when a clot floats in and finishes making a blockage.

Question 2

why is exercise important with coronary artery disease? wouldnt exercise cause a greater blockage and cause a heart attack?

Accepted Answer

: Exercise helps to lower cholesterol and reduce the risk of cardiovascular disease. If someone has cardiovascular disease, there can still be a reduction in disease with exercise. Some people with severe cardiovascular disease can't exercise because of active disease symptoms

Question 3

artery heart blockage mild,what are the risks of having a heart attack? thanks

Accepted Answer

About 20% over 10y: If you have ever had a heart attack before, and you are not having major heart symptoms now, then your risk for a heart attack or stroke over the next 10 yrs is about 20%. Taking 40-80 mg of atorvastatin daily would decrease risk to about 10%. Visit my website, http://CardioGauge.com for info about calculating risk for heart attack and stroke. Good luck!

Question 4

what are my chances of having artery blockage or a heart attack after a normal nuclear stress test?

Accepted Answer

Very small : A myocardial perfusion scan done in good hands and at a good workload, i.e. Achieved &gt; 85% max predicted heart rate that is normal bodes well for u. Typically if totally normal, your risk of an adverse cardiovascular outcome is less than 1% over next 3 years. At your young age, you ought not to get another nuclear scan if no symptoms, but rather focus on a heart heathy lifestyle. Mediterraneandiet

Question 5

how do i reduce the risk of a heart attack via coronary artery blockage?

Accepted Answer

Proactive care: Big topic. Briefly: maintain healthy weight, exercise regularly, eat healthy diet, don't use tobacco, limit alcohol consumption, manage stress, have regular physicals with a physician focused on proactive care. Eval generally looks for high blood pressure, diabetes/pre-diabetes/insulin resistance, cholesterol panel. More advanced "cholesterol" testing is available and better at predicting risk.

Question 6

can you have a heart attack from a blockage in any of the three different arteries carotid, coronary or peripheral?

Accepted Answer

Heart attack: The coronary arteries provide vascular flow to the heart and if obstructed can cause a myocardial infarction compromising the cardiac pump.  The carotid obstruction would cause a stroke in the brain, and peripheral block in legs could result in gangrene

Question 7

i am 54, previous heart attack.  now have mild blockage in the right carotid artery and moderate/ severe in the left so i am told.  cta shows 50% blockage on both sides.  the left carotid artery has a velocity in the 400's. how should they treat this?

Accepted Answer

Carotid stenosis: Agree with Dr Fowler, as you would highly benefit from a telemedicine virtual consult with one of our superlative HT physicians 
A vascular surgeon could also provide excellent guidance and is another worthwhile visit.

Question 8

can i ride a roller coaster 3 years after having a heart attack due to blockage of the right coronary artery and getting stents implanted?

Accepted Answer

Enjoy ride: Hope you are not doing the tallest and fastest roller coaster.

Question 9

i had a major heart attack in aug 2012 with 100 percent blockage in lad and one stent is inserted please give precaution?

Accepted Answer

Do this:: Don't smoke. Eat vegetarian. Exercise 20-30 minutes daily. Try to be normal weight. Keep BP under control. Take aspirin, a beta blocker, and a statin every day without fail. You can live a long life. Be well.

Question 10

i had a heart attack last week. the ecg was clear. angiogram showed healthy arteries with no blockages. bloodtest=0.40 of troponin.what caused it?

Accepted Answer

Hard to say: Many things (including renal failure, pulmonary embolus, etc) can cause a mild elevation of troponin.  If an ekg and a coronary angiogram were negative i doubt that the elevated troponin was caused by a heart attack.
