What lifestyle change is crucial for reducing the risk of ACS?

Smoking cessation is a crucial lifestyle change for reducing the risk of Acute Coronary Syndrome (ACS). Cigarette smoking is a significant modifiable risk factor for cardiovascular diseases, including heart attacks and other forms of ACS. The harmful substances in cigarette smoke damage the blood vessels, increase blood pressure, reduce oxygen supply to the heart, and contribute to the formation of clots. By quitting smoking, individuals can significantly lower their risk of developing coronary artery disease and experiencing ACS. The benefits of smoking cessation extend beyond heart health, as it also improves overall health and reduces the risk of various chronic diseases.

The other options involve behaviors that could potentially increase health risks rather than mitigate them. Increasing caffeine intake may raise blood pressure and impact heart health in some individuals. A high-sugar diet is linked to obesity and other metabolic syndrome components, while limiting hydration can lead to dehydration, which is detrimental to overall cardiovascular and health status.
