Both angina symptoms and diagnosis have a significant adverse effect on survival among men aged 70-90 years highlighting the importance of diagnosis and appropriate treatment of angina in old age.
How is Prinzmetal's diagnosed?
So, the things doctors look for to diagnose Prinzmetal angina are:
- typical "anginal" chest pain,
- accompanied by dramatic changes on the ECG,
- which are relieved by nitrate administration,
- with "normal' coronary arteries demonstrated on cardiac catheterization.
What does prinzmental angina mean?
Prinzmetal’s angina is a form of chest pain, pressure, or tightness (angina) caused by spasms in the arteries that supply blood to the heart. It is a form of unstable angina, meaning that it occurs at rest, often without a predictable pattern. This is in contrast to stable angina, in which chest pain occurs in a predictable pattern during exertion or exercise.
What are the remedies for angina?
“This sizable and important subgroup of the population deserves much more attention in research focusing on cardiovascular disease prevention and treatment.” Angina in NHANES Herbert et al say NHANES presents a unique opportunity to study this ...
What is the preferred treatment for variant or prinzmetal angina?
Treatment of Variant Angina (Prinzmetal) Angina Medicines can help control the spasms. Drugs such as calcium antagonists and nitrates are the mainstays of treatment.
What drugs treat variant angina?
Isosorbide dinitrate is used for the treatment and prevention (sustained-release preparations) of variant angina. The onset of action is approximately 3.5 minutes, and the antianginal effect lasts about 2 hours.
Which drug is the first choice for the treatment of variant angina pectoris?
Calcium channel (Ca) blockers are used as the first choice and effective agents for vasospastic angina pectoris.
Which drug group is most effective for the treatment of variant vasospastic angina?
Nitrates or beta blockers are usually preferred for initial treatment of angina, and calcium channel blockers may be added if needed.
Is amlodipine used in variant angina?
Amlodipine (Norvasc) It is appropriate for prophylaxis of variant angina.
Why beta-blockers are contraindicated in Prinzmetal angina?
Beta-blockers can increase coronary artery spasm and cause chest pain so they are contraindicated in these patients.
Which agent would be most appropriate for a client with Prinzmetal angina?
Managing Prinzmetal's Angina: CCBs have long been preferred for treating Prinzmetal's angina. SL nitroglycerin or IV nitrates may be used for initial relief of an acute attack. Similar to unstable angina, Prinzmetal's angina may respond to long-acting nitrates, but response to BBs varies.
Which of the following is the best treatment for angina?
Nitrates or beta blockers are usually recommended first for people with stable angina. Calcium channel blockers are an alternative if there are side effects or other conditions that limit the use of beta blockers and nitrates.
What is the first line treatment for angina?
Beta-blockers are an appropriate first-line medical treatment to relieve the symptoms of angina. Calcium channel blockers or long-acting nitrates may be appropriate for those who do not tolerate or who have contraindications to beta-blockers.
How is variant angina treated?
Variant angina is often treated with medications called calcium channel blockers. These medications can decrease variant angina attacks and are often used in combination with nitrates during attacks.
Which drugs are considered the drugs of choice for vasospastic angina?
Beta Blockers: propranolol, metoprolol, atenolol. Calcium Channel Blockers: nifedipine, verapamil, diltiazem.
Which calcium channel blocker is best for coronary vasospasm?
Amlodipine, the most widely used second generation CCB for VA, is also widely used as an antihypertensive agent, because it has excellent blood pressure lowering effects. For VA patients who need blood pressure control, amlodipine may be the first choice.
Overview
Prinzmetal angina is a rare and sometimes severe type of angina (chest pain). It usually happens between midnight and the morning while you’re asleep or resting. Prinzmetal (or Prinzmetal’s) angina is also called variant angina, angina inversa and vasospastic angina.
Diagnosis and Tests
Your provider may do the following tests to diagnose Prinzmetal angina.
Management and Treatment
Prinzmetal angina is treated with medications and lifestyle changes. The types of drugs used to treat Prinzmetal angina include:
Living With
If you have any type of chest pain, you should contact your healthcare provider. They are likely to run tests to see what’s causing the pain. If you have severe chest pain, go to the emergency room or call 911. This can be an emergency.
When does Prinzmetal angina occur?
Unlike typical angina – which is often triggered by exertion or emotional stress – Prinzmetal’s angina almost always occurs when a person is at rest, usually between midnight and early morning. These attacks can be very painful.
What are the different types of angina?
Prinzmetal angina may also be referred to as: 1 Variant angina 2 Prinzmetal's variant angina 3 Angina inversa
How long does it take for Prinzmetal to stop working?
After six to 12 months of treatment, doctors may gradually reduce the medication. Prinzmetal's angina is a chronic condition that will need to be followed by your healthcare provider even though the prognosis is generally good. Track your angina symptoms with our Angina Log.
Why does my angina hurt?
Causes of Variant (Prinzmetal) Angina: The pain from variant angina is caused by a spasm in the coronary arteries (which supply blood to the heart muscle). The coronary arteries can spasm as a result of: Exposure to cold weather. Stress.
Is Prinzmetal's angina rare?
Angina inversa. Prinzmetal’s angina is rare, representing about two out of 100 cases of angina, and usually occurs in younger patients than those who have other kinds of angina.
METHODS AND DEFINITIONS
Prinzmetal’s variant angina is diagnosed by a combination of historic and diagnostic procedures. We require that the patient have episodes of typical myocardial ischemic chest pain that occur spontaneously at rest, or awaken the patient from sleep. These anginal episodes should respond to sublingual nitroglycerin.
MEDICAL THERAPY
Angina due to coronary artery spasm typically responds rapidly to sublingual nitroglycerin in doses of 0.3 to 0.6 mg. Incomplete responders may require a repeated dose. Although isosorbide dinitrate can also be used sublingually, it appears to offer little benefit over nitroglycerin.
AUTONOMIC BLOCKING AGENTS
The occurrence of coronary artery spasm at night, and its provocation with methacholine, has implicated the parasympathetic nervous system in the etiology of this disease.
CALCIUM ANTAGONISTS
This group of pharmacologic agents is composed of chemically dissimilar drugs that block the slow-channel movement of calcium into the cell. They have been demonstrated to have potent coronary artery vasodilatation effects, resulting in notable increases in coronary flow.
RESULTS
Preliminary results in eight patients showed dramatic response to both the 30- and 60-mg (four times daily) dosage of diltiazem ( Table 2 ).
SUMMARY
Nitroglycerin remains highly effective and the drug of choice for the acute treatment of angina due to coronary artery spasm. Long-acting nitrates and α-blockers are only partially useful for prophylaxis of angina attacks because of the high frequency of adverse side effects at therapeutic levels of these drugs.

How long does chest pain last with Prinzmetal's angina?
Episodes of chest pain caused by Prinzmetal’s angina usually occur in clusters, with periods of frequent episodes lasting for a few months followed by weeks or months with no chest pain episodes.
Why does Prinzmetal cause chest pain?
The chest pain of Prinzmetal’sangina is caused by coronary artery spasm, an abnormal or involuntary constriction of the muscle in a coronary artery. This spasm makes the diameter of the artery smaller, restricting the supply of blood and oxygen to the heart, causing chest pain. In rare cases if the spasm is not.
Why does Prinzmetal pain occur?
The pain usually occurs between midnight and approximately 8:00 AM. Prinzmetal’s angina may be brought on by hyperventilation, exposure to cold, or extreme emotional stress. Prinzmetal’sangina is named after the researcher who first noted that coronary artery spasms were to blame. It is also called variant angina because of the unusual pattern ...
What is the best medicine for chest pain?
If you continue to experience episodes of chest pain, then a different class of calcium channel blocker or a long-acting nitrate may be given. Nitroglycerin is used when you are experiencing a spasm to stop it, thereby alleviating pain; it is not used as a preventive medication.
What is Prinzmetal used for?
Prinzmetal’sangina is treated with medications, specifically nitroglycerin (NTG), long-acting nitrates, and calcium channel blockers, all of which widen or open the blood vessels and improve blood and oxygen flow to the heart muscle. Calcium channel blockers are generally prescribed first.
Can Prinzmetal cause sudden death?
There is also a very slight risk of sudden death (about 2%) in people with Prinzmetal’s angina.Coronary artery spasms can also be silent, meaning they occur without any symptoms. Described as squeezing, constricting, tightness, pressure, or crushing, which is usually severe and may radiate to the neck, jaw, shoulder, or arm.
