How does nitroglycerin work to relieve chest pain?

Nitroglycerin: Nitroglycerin relieves cardiac related chest pain by dilating the coronary arteries. These are the arteries that supply blood to the heart. Improving blood flow to heart muscle will relieve the discomfort caused by a partial blockage of the blood vessel with plaque. ...Read more

What to do if I'm having chest pain on the left side and had nitroquick (nitroglycerin) time2 help?

Chest pain: If you have chest pain and have taken Nitro without any improvement then you should be seen by a physician right away. You should go to an ER for evaluation. If it is not serious then you can follow with your regular physician, if it is then you will be admitted for further testing, but don't wait. ...Read more

I am on Imdur ER 60mg and Nitroglycerin. 4mg. My BP is 80/60... I am having chest pain. Is it safe to take my nitro with that BP?

Lying down: It is surprising to me that a 23 year old would have significant enough coronary artery disease to require these medications. Nitroglycerin will briefly lower your blood pressure more which could be detrimental. If you are lying down when you take it you may not pass out or feel as dizzy. I think you need to confirm the need for these medications with your health care provider. ...Read more

I have chest pain. Cleared by Heart MD. ALL other system R/O. Put on Imdur ER and Nitrostat (nitroglycerin). They are only things that help. Is ok to take long term?

Diagnosis?: U say that ur Heart MD (presumably a Cardiologist) "cleared" you. What does that mean? What is the diagnosis? Do you have Prinzmetal's angina (ie coronary artery spasm with no blockage)? Is it Diffuse Esophageal Spasm, which mimics chest pain? In pts with heart disease (CAD), being on long-term nitrates increase mortality; however, u r young (23) & probably don't have CAD. Again, ask ur "heart MD" ...Read more

I've been taking nitroglycerin for episodes of chest discomfort (was prescribed by cardiologist to see if it helped). I don't notice much relief from it. Does this indicate it's not artery spasms?

Not necessarily: The crucial question you are asking is 'do I have cardiac disease, and is the chest discomfort I am experiencing due to this heart disease'? Ntg test does not do much to help to get to the answer to the question. Further testing needs to be done, such as an echocardiogram (which gives more info about the heart valves), stress testing and angiogram, which tells info about the coronary vessels. ...Read more

Having chest pain, shortness of breath (3 months)ekg, echo, stress, Ca score, and blood work all normal. What could it be? Can I stop worrying about heart?

Having chest pain, shortness of breath (3 months)ekg, echo, stress, Ca score, and blood work all normal. What could it be? Can I stop worrying about heart?

Unlikely heart: The odds are in your favor significantly that you can stop worrying about your heart. The probability even without such extensive testing for someone your age is very low for your chest pain and shortness of breath being due to a heart abnormality. I would begin looking into pulmonary issues as an alternative; however, I think learning relaxation techniques is more likely to provide benefit. ...Read more

Physical exam would hear wheezing related to asthma. A common problem is walking pneumonia or mycoplasma pneumonia which many radiologists do not recognize subtle interstitial findings on radiograph.

Physicians trained &: Paid to look only for evidence of advanced disease. Though known >8 decades (via autopsies in US) that 1/2 population has arterial disease by age 7, humans compensate, arteries enlarge (not narrow) in compensation, thus no symptoms/signs for decades, EKGs miss the problem.

Why after stressful situation, I got mild chest pain&tightness, upper left arm pain for 10 hours.2 times I went to ER but EKG blood work, X-ray were ok?

Evaluation: It sounds like it's time for a more thorough evaluation by a doctor with a stress test and re-evaluation of your blood pressure and cholesterol. Often cardiac symptoms do not produce abnormal ekg, x-ray or blood testing in the emergency room. You are of an age, with classic worrisome symptoms, that it's worth the time & effort. ...Read more
