Heart transplants are complex, costly, and risky—but for patients with heart failure, they are often the only option for survival. Now, a groundbreaking study suggests that a natural supplement may help certain heart failure patients recover without surgery.
Researchers from Osaka University have discovered that tricaprin, a dietary supplement, can significantly improve survival rates and even reverse heart damage in patients with triglyceride deposit cardiomyovasculopathy (TGCV). Their findings, published in Nature Cardiovascular Research, provide new hope for patients who previously had no effective treatment options.
What Is TGCV and Why Is It Dangerous?
TGCV is a newly identified heart disease caused by the buildup of triglycerides (a type of fat) in heart and blood vessel cells. When these fats accumulate, they damage the heart muscle and arteries, leading to severe symptoms, clogged arteries, and ultimately heart failure.
For many patients with TGCV, heart failure progresses to the point where a transplant is needed. However, this study suggests that tricaprin could be a life-saving alternative.
How Tricaprin Helped Patients Recover
To understand tricaprin’s long-term effects, researchers analyzed data from 22 TGCV patients who took the supplement and compared them with 190 control patients who did not. They also matched 81 controls to ensure a fair comparison based on age, heart condition, and other risk factors.
The results were remarkable:
- 100% of tricaprin patients survived for at least 3 and 5 years, compared to only 78.6% and 68.1% in the control group, respectively.
- Many patients saw significant improvements in heart function and a reversal of structural damage caused by the disease.
- Even patients on hemodialysis, who typically have very poor survival rates, benefited from tricaprin.
Dr. Ken-ichi Hirano, the study’s lead author, emphasized how life-changing this supplement could be. “Not only did patients’ symptoms improve, but their heart function and structure actually recovered,” he said.
How Does Tricaprin Work?
Tricaprin is a medium-chain triglyceride (MCT) that helps break down excess fat stored in the heart. The researchers believe that capric acid (C10:0), a key component of tricaprin, plays a crucial role by activating fat-clearing enzymes.
Unlike some other fat breakdown processes, tricaprin’s effects do not rely on a specific enzyme (ATGL). This means it may work even in patients who have genetic issues with fat metabolism.
The Future of Tricaprin as a Treatment
While these results are promising, the study was conducted only on Japanese patients. The next step is to test tricaprin in diverse populations to confirm its effectiveness across different ethnicities.
Dr. Hirano hopes that raising awareness about TGCV will lead to earlier diagnosis and treatment, giving patients a better chance of recovery. If further studies confirm its benefits, tricaprin could become a game-changing, non-invasive treatment for certain types of heart failure—helping many patients avoid the need for a transplant altogether.
