What are the characteristics of myocardial infarction in young people? Summary of recent research results

It is not uncommon for people to suffer myocardial infarction at a young age. An analysis of 24,000 patients conducted by the China Acute Myocardial Infarction Registry (CAMI) showed that 8.5% of patients with acute myocardial infarction were ≤45 years old.

What are the characteristics of young patients with myocardial infarction?

Multiple studies have highlighted four issues: male gender, smoking, obesity, and dyslipidemia.

For example, an article in Cardiovascular Research pointed out that the risk factors for myocardial infarction in patients under 45 years old are as follows: smoking, obesity, being male, familial mixed hyperlipidemia, and family history of coronary heart disease.

These are the results of a large number of studies:

For example, a recent study conducted by Li Hongwei and others from Beijing Friendship Hospital showed that among men under the age of 50 who suffered myocardial infarction, 77.1% smoked, 26% were obese, and 74.7% had abnormal blood lipids.

A study published in our journal by Song Xiantao and others from Beijing Anzhen Hospital showed that for people aged 18 to 44 who have just had their first myocardial infarction, the modifiable risk factors are smoking (72.7%), hypertension (40.8%) and obesity (37.8%).

Another analysis by CAMI showed that young men with myocardial infarction had more severe dyslipidemia. For example, among patients with LDL-C ≥ 4.1 mmoL/L, the proportion of young men was higher than that of older men.
