Diagnosing toxin-induced cardiovascular events requires a combination of clinical evaluation and laboratory tests. Biomarkers such as troponin levels, electrocardiograms (ECG), and imaging studies are essential tools in the diagnostic process. Treatment focuses on alleviating symptoms, managing complications, and removing the source of toxicity. Chelation therapy, for instance, is used in cases of heavy metal poisoning, while supportive care and medications address cardiovascular symptoms.
