Cardiovascular Health and Heavy Metal Burden: An Emerging Conversation in Palm Beach County

June 19, 2026; By Benjamin Kosubevsky

In Palm Beach, Palm Beach Gardens, and Wellington—communities where residents invest significantly in their cardiovascular health through diet, exercise, and preventive cardiology—an emerging body of research is raising questions about a factor that most standard cardiac evaluations do not assess: cumulative heavy metal burden.

The Connection Between Heavy Metals and Cardiovascular Risk

Peer-reviewed research has identified associations between chronic heavy metal exposure and cardiovascular disease risk. Lead, cadmium, mercury, and arsenic have each been studied for their potential effects on endothelial function, oxidative stress, and inflammatory pathways in the vascular system. A comprehensive review in EXS documented the multi-system toxicity of these metals, including their cardiovascular implications (Tchounwou et al., EXS, 2012).

A separate review examined the mechanisms by which specific metals may contribute to atherosclerosis, hypertension, and other cardiovascular pathology, noting that the relationship between chronic low-level exposure and long-term cardiovascular outcomes is an area of active scientific investigation (Jaishankar et al., Interdisciplinary Toxicology, 2014).

The TACT Trial: A Landmark Study

The most significant clinical evidence connecting chelation therapy to cardiovascular outcomes comes from the Trial to Assess Chelation Therapy (TACT). This NIH-funded, randomized, double-blind, placebo-controlled trial enrolled 1,708 patients aged 50 and older with a history of myocardial infarction. Patients receiving 40 IV EDTA chelation treatments showed a statistically significant reduction in a composite endpoint of death, reinfarction, stroke, coronary revascularization, and hospitalization for angina, compared to placebo (Lamas et al., JAMA, 2013). The effect was especially pronounced in diabetic participants, where the chelation group experienced a 41% relative reduction in the primary endpoint. A follow-up study, TACT2, was subsequently funded to further investigate these findings in diabetic patients specifically.

What This Means for Palm Beach County Residents

For health-conscious residents of Palm Beach, Palm Beach Gardens, and Wellington who are already engaged in proactive cardiovascular care, heavy metal testing represents a relatively simple addition to their existing health surveillance. If elevated levels are found, chelation therapy may be worth discussing with a physician who understands both the TACT evidence and the limitations of the current data.

At The Longevity Center FL in West Palm Beach, Dr. Kosubevsky offers both heavy metal testing and IV EDTA chelation therapy for patients whose laboratory findings and clinical profile support its use.
