Linked Cholesterol Medications Associated with Decreased Lung Function Capacity

Uncovering the Effects of Statins and a New Class of Cholesterol Drugs on Health

Over the past few decades, the use of statins, a popular cholesterol-lowering medication, has remained contentious, often stemming from debates over the lipid hypothesis. As patients reported side effects, such as muscle pain, the controversy deepened.

Now, decades later, the list of potential side effects has grown, along with the number of Americans diagnosed with heart disease. It's crucial for individuals to understand the risks associated with statins and other drugs before making informed decisions about their use.

Recent research, conducted by the University of South Australia, delves deeper into this discussion. The university's team completed one of the world's largest studies on drugs designed to treat cholesterol, comparing these medications to a variety of clinical and heart and brain MRI biomarkers.

Their findings shed light not only on statins but also on PCSK9 inhibitors, a newer class of cholesterol drug that received FDA approval in 2015.

Statins, which are known for lowering the liver's cholesterol production, were found to correlate with higher BMI and body fat, as well as reduced testosterone levels. For both men and women, reduced testosterone can lead to reduced sex drive, lack of energy, decreased strength, muscle tone, and bone mass. Testosterone also plays a significant role in heart and blood vessel health.

An unexpected finding was that some people experienced an increase in brain volume of the hippocampus, which may potentially reduce the risk of dementia and depression. However, it's unclear whether these individuals were taking lipophilic statins, which have been associated with dementia in another study.

PCSK9 inhibitors, on the other hand, work differently. Unlike statins, PCSK9 inhibitors go after and destroy cholesterol already in our cells. They may impair lung function, particularly in individuals with conditions like asthma or sleep apnea.

UniSA PhD student Kitty Pham, the lead author of the paper, believes that these findings will help medical professionals understand how people respond to different drugs and assess the viability of new drug pathways.

As we continue to learn more about these cholesterol-lowering drugs, it's important for physicians to prescribe them with caution, considering each patient's unique needs. Meanwhile, it's worth remembering that drug-free methods, such as healthy diets, exercise, and stress management, can also play a significant role in controlling cholesterol levels and reducing the risk of heart disease.
