Hidden Chemical in Capsules Linked to Heart Attack Risks

A prominent cardiologist has uncovered a concerning chemical present in medicine capsules that may heighten the risk of heart attacks. Dr. Evan Levine from Mount Sinai in New York has indicated that phthalates, which are used to enhance the flexibility of plastics in soft gel capsules, could pose significant health threats.

Phthalates, often referred to as plasticizers, make materials soft and durable, allowing for various shapes and resilience in different conditions. However, research has shown that once these compounds enter the body, they can irritate arteries and promote inflammation, complicating blood flow to and from the heart.

These chemicals are commonly found in soft gel capsules, which are often used for pain relief, multivitamins, stool softeners, and medications for colds and coughs. Dr. Levine advises people to moderate their intake of such capsules. Interestingly, although the exact number of Americans consuming these capsules is unclear, the market for soft gel capsules was valued at around $2.14 billion in 2022.

Dr. Levine remarked, “Phthalates can increase inflammation, which is a significant risk factor for heart disease.” A study conducted in 2021 revealed that exposure to phthalates was linked to a slightly elevated risk of death from cardiovascular issues.

The research analyzed urine samples from over 5,300 adults aged 55 to 64 from 2001 to 2010, tracking mortality causes within that group. The findings indicated that individuals with higher levels of phthalates in their urine were more likely to have died from heart conditions during the study period.

While further investigation is necessary to clarify the relationship between phthalates and heart problems, Dr. Levine emphasizes that ingesting these chemicals, particularly through medications, can trigger inflammation in the arteries that supply blood to the heart. This can lead to narrowing or hardening of arteries, heightening the risk of blockages or aneurysms.

Typically, such conditions are caused by cholesterol and other substances building up along artery walls, forming plaques. However, excessive exposure to phthalates can also contribute to this inflammation.

Experts believe that these chemicals may also induce oxidative stress—this imbalance can harm heart cells, impairing their function and potentially resulting in further inflammation and thickening of arterial walls, thereby increasing heart attack risk.

Additionally, phthalates might adversely affect cholesterol and triglyceride levels in the body, increasing susceptibility to strokes and heart disease.
