Lifestyle, not genetics, explains most premature heart disease

Physical inactivity, smoking, high blood pressure, diabetes, and high cholesterol play a greater role than genetics in many young patients with heart disease, according to research presented today at ESC Congress 2019 together with the World Congress of Cardiology. The findings show that healthy behaviours should be a top priority for reducing heart disease even in those with a family history of early onset.

“Genetics are an important contributor to premature heart disease but should not be used as an excuse to say it is inevitable,” said study author Dr Joao A. Sousa of Funchal Hospital, Portugal.

“In our clinical practice, we often hear young patients with premature heart disease ‘seek shelter’ and explanations in their genetics/family history,” he added. “However, when we look at the data in our study, these young patients were frequently smokers, physically inactive, with high cholesterol levels and high blood pressure — all of which can be changed.”
