Regular exercise significantly impacts lipid profiles, particularly in cardiac patients, by lowering low-density lipoprotein (LDL) cholesterol and increasing high-density lipoprotein (HDL) cholesterol. LDL cholesterol is often referred to as "bad" cholesterol, which can contribute to the buildup of plaques in arteries, increasing the risk of cardiovascular disease. Conversely, HDL cholesterol is known as "good" cholesterol because it helps remove LDL cholesterol from the bloodstream and prevent atherosclerosis.

Engaging in regular physical activity promotes various physiological changes in the body, including improved metabolism and enhanced lipid transport mechanisms. Aerobic exercises, such as walking, running, cycling, and swimming, have been shown to upregulate enzymes that increase the clearance of triglycerides from the bloodstream and enhance the production of HDL. This shift in lipid profiles is especially beneficial for cardiac patients as it contributes to overall cardiovascular health and reduces the risk of events such as heart attacks and strokes.

In the context of the other options, they do not align with the well-established effects of exercise on lipid profiles. Raising LDL cholesterol or having no effect on lipid profiles contradicts the findings in clinical studies. Additionally, primarily increasing triglyceride levels would be contrary to the general benefits of exercise, as regular activity typically leads
