This study aimed to evaluate the seroprevalence of Toxoplasma gondii in cardiovascular patients in Western Romania. The results showed that the overall seroprevalence of T. gondii antibodies was 64.06% in cardiovascular patients and 52.88% in blood donors. Compared to the control group, a significantly higher prevalence of T. gondii antibodies was found among patients with hypertension and unstable angina. This study provides valuable information for further research on the impact of T. gondii exposure on cardiovascular patients.
(1) Background: Toxoplasma gondii infects approximately one third of the world's human population. The seroepidemiology of T. gondii in cardiovascular patients is poorly discussed in the existing literature. We aimed to evaluate, for the first time, the seroprevalence of T. gondii in cardiovascular patients from Western Romania. (2) Methods: Serologic testing to demonstrate the presence of T. gondii antibodies was conducted in 256 patients with cardiovascular diseases and 261 matched blood donors. (3) Results: The overall seroprevalence of T. gondii antibodies was 64.06% in patients with cardiovascular diseases and 52.88% in blood donors and tended to increase with age in both groups. The seroprevalence of T. gondii antibodies was significantly higher in cardiovascular male patients (69.94%) compared to male blood donors (55.69%) (p = 0.006). When compared to the control group, a significantly higher prevalence of T. gondii antibodies was found among patients with hypertension (82.35%; p = 0.01) and unstable angina (67.56%; p = 0.02). (4) Conclusions: This study brings new epidemiological information on the prevalence of T. gondii in Romanian cardiovascular patients. T. gondii seroprevalence was significantly higher in patients with hypertension and unstable angina, suggesting that individuals with these diagnoses may be more frequently infected with T. gondii. This study may be a valuable starting point for further research to better evaluate the impact of T. gondii exposure on patients with cardiovascular diseases.
