What is the reported mortality range for the cardiac form?

The main idea here is the poor prognosis once the heart is affected by this infection. When the cardiac form develops, the heart suffers chronic damage from ongoing inflammation, leading to dilated cardiomyopathy, arrhythmias, and heart failure. This level of cardiac involvement carries a substantial risk of death over time, which is why the range around half to nearly three-quarters of patients are reported as mortality. In studies, mortality for the cardiac form commonly falls in the 50–70% range, reflecting deaths from progressive heart failure or sudden cardiac events. The other ranges are not consistent with the level of risk seen with cardiac involvement, which is much higher than 0–5% or 10–20% but not as universally fatal as 80–90%.
