Sepsis-induced myocardial dysfunction (SIMD) is a common and clinically significant complication in critically ill patients with sepsis and septic shock. This systematic review confirms that SIMD is consistently linked to greater overall disease severity, increased reliance on vasopressors, and more pronounced organ dysfunction. However, the analysis found that current evidence does not conclusively establish SIMD as an independent predictor of mortality.

This uncertainty is largely attributed to methodological inconsistencies, small sample sizes, and a lack of standardized diagnostic criteria across the included studies.

Despite SIMD’s clear association with sicker patients, its direct, independent impact on survival remains a mystery, especially since the dysfunction often resolves quickly in patients who recover.

Consequently, current data do not support using targeted inotropic agents like levosimendan as a definitive strategy to reduce mortality.

Future multicenter research is strongly recommended to use standardized definitions and incorporate longitudinal follow-up to finally determine if directly treating SIMD can significantly improve both survival and long-term recovery in this vulnerable ICU population.
