Who Is Most at Risk for Prinzmetal (Vasospastic) Angina?

While anyone can develop Prinzmetal angina (also known as vasospastic angina), certain groups of people are noticeably more likely to get it. Unlike stable or exertional angina—which typically affects older adults and is caused by obstructive coronary disease (plaque buildup)—Prinzmetal angina often occurs while resting, particularly late at night or early in the morning ^[1]. It can affect relatively younger patients and frequently occurs in people who do not have traditional heart disease risk factors like high cholesterol, high blood pressure, or diabetes ^[2][3]. Epidemiological research also shows a higher frequency of the condition in East Asian populations, particularly in Japan, compared to Western populations ^[4][1].

Urgent Safety Warning

No matter your risk factors, chest pain should never be ignored. Prinzmetal angina can cause dangerous heart rhythms or a heart attack. If you experience new, severe, persistent, or recurring chest pain—especially accompanied by shortness of breath, fainting, sweating, nausea, or palpitations—seek emergency medical attention immediately. Do not wait for a routine appointment or specialized testing.

The Role of Ethnicity and Geography

Research shows that Japanese and other East Asian populations have a higher reported rate of Prinzmetal angina than Western populations. For example, one review of patients who had chest pain but no obstructed arteries found coronary artery spasms in about 52% of the Asian patients studied compared to 33% of the Western patients ^[4].

This difference may be due to a combination of genetic associations and how doctors diagnose the condition:

• Genetic Susceptibility: A specific genetic variant known as the ALDH2*2 allele is prevalent in East Asian populations and has been associated with an increased risk of coronary artery spasms ^[5]. However, having this variant does not mean you will definitively develop the condition, and routine genetic testing is not currently standard.
• Diagnostic Practices: Doctors in Japan frequently use specialized provocation tests (invasive tests that use medication to trigger a spasm in a highly monitored hospital setting) ^[1]. Because of differences in healthcare systems and testing protocols, the condition may be diagnosed more frequently in some regions than others. Note that provocation testing carries risks and is not automatically appropriate or necessary for every patient.

Is Prinzmetal Angina Genetic?

Many patients wonder if they inherited this condition from their parents. While Prinzmetal angina is not considered a traditional “inherited disease” caused by a single faulty gene, there is evidence of familial susceptibility ^[6].

A nationwide family study found that siblings of people with vasospastic angina have a higher risk of developing the condition themselves ^[6]. Interestingly, the spouses of those patients did not show an increased risk. This supports the idea that the shared risk among siblings is likely due to genetic susceptibility or shared early-life factors, rather than the shared adult environment ^[6].

Age, Triggers, and Lifestyle Factors

One of the distinguishing features of Prinzmetal angina is who it affects and what triggers it:

• Age Profile: While classic obstructive heart disease often takes decades to build up, Prinzmetal angina can occur at younger ages, though it affects older adults as well ^[2].
• Lack of Major Blockages: Many people diagnosed with this condition have angiographically unobstructed arteries (no major blockages seen) and normal cholesterol levels ^[7]. However, traditional risk factors like high blood pressure and diabetes still matter for your overall cardiovascular health and should always be managed ^[3].
• The Smoking Factor: The strongest and most consistently identified modifiable risk factor for developing Prinzmetal angina is cigarette smoking ^[8]. Studies show that smoking significantly increases the odds of experiencing coronary spasms ^[9]. If you smoke, quitting is one of the most important steps you can take for your heart.
• Other Triggers: Certain substances can provoke spasms. These include recreational drugs like cocaine and amphetamines, as well as some prescription medications, such as specific migraine drugs (triptans), certain cold medicines (decongestants), and stimulants ^[10][11]. Emotional stress and cold exposure can also be triggers for some patients. Never stop or change prescribed medications without consulting your doctor.
