Taiwanese doctor highlights 'skinny needle' drug's heart benefits beyond weight loss

Beyond its widespread use for weight loss, the "skinny needle," medically known as a GLP-1 receptor agonist, is emerging as a significant tool for protecting cardiovascular health, according to a physician in Kaohsiung.

Many patients think that having a stent means their heart disease has been cured. In fact, the stent only opens up blocked blood vessels; the atherosclerosis that causes the disease may continue to progress.

Dr. Wu Yiting, a cardiologist at Kaohsiung Municipal United Hospital, explained that while stents open blocked arteries, the underlying atherosclerosis can continue to progress. Effective management of blood pressure, blood sugar, blood lipids, and weight remains crucial to prevent major cardiovascular events like heart attacks and strokes. The GLP-1 receptor agonists, initially developed for type 2 diabetes, work by mimicking natural hormones to enhance feelings of fullness, slow stomach emptying, and consequently help control blood sugar and weight.

The reason why GLP-1 drugs have received much attention from the medical community in recent years is not only their good weight loss effect, but also that multiple large international studies have found that they can reduce the risk of myocardial infarction, stroke, and cardiovascular death.

Dr. Wu highlighted that recent international research has underscored the cardiovascular benefits of these drugs. A notable study published in The New England Journal of Medicine in 2023, the SELECT trial, demonstrated that GLP-1 receptor agonists effectively lowered the incidence of major cardiovascular events in obese patients with cardiovascular disease, even if they did not have diabetes. The drugs are thought to offer benefits beyond weight and glucose control, potentially including anti-inflammatory effects, improved vascular function, and better blood pressure and lipid profiles.

However, Dr. Wu cautioned that these "skinny needles" are not suitable for everyone. Common side effects include nausea, bloating, and gastrointestinal discomfort. As prescription medications, they require a thorough professional assessment by a physician based on an individual's health status, medical history, and risk factors. He emphasized that consistent medication, a healthy diet, and regular exercise are essential for effectively reducing the risk of cardiovascular disease recurrence.
