Insights
Cardiogenic shock (CHC) following myocardial infarction has high mortality. Measuring cardiac power after reperfusion can identify high-risk patients, improving treatment strategies for better outcomes.
Area of Science:
- Cardiology
- Critical Care Medicine
Context:
- Cardiogenic shock (CHC) complicating acute myocardial infarction presents heterogeneous manifestations and historically high mortality rates.
- Institutional mortality for CHC was reduced from 98% to 53% with the implementation of reperfusion therapies.
Purpose:
- To evaluate the utility of clinical stratification and hemodynamic assessment, specifically cardiac power, in managing patients with cardiogenic shock post-myocardial infarction.
- To identify predictors of mortality in CHC patients undergoing reperfusion procedures.
Summary:
- Clinical stratification involves assessing age, infarction location, heart rate, and systemic arterial pressure.
- Hemodynamic evaluation using right heart catheterization quantifies myocardial work parameters, including "Cardiac Power" (cardiac output x mean arterial pressure).
- In this experience, patients with CHC and cardiac power < 1.0 after reperfusion demonstrated significantly higher mortality.
Impact:
- Opportune clinical and hemodynamic stratification can significantly improve treatment strategies for CHC.
- Identifying patients with low cardiac power (< 1.0) post-reperfusion allows for targeted interventions to mitigate high mortality risks.
Abstract:
Cardiogenic shock (CHC) associated to acute myocardial infarct has high mortality and their manifestations are heterogenous. In our institution historical mortality, was 98%, but with different methods of reperfusion, its reduced to 53%. In other hand, with opportune clinical stratification is useful to improve the treatment strategy. This stratification on basis in clinical signs: age, infarction location, cardiac frequency and systemic arterial pressure, and hemodynamical valuation with the use of right catheterism with quantification miocardial work parameters like "Cardiac power" that is the product of flow and arterial pressure and that is of utility to know the "Miocardial reserve". In our experience after reperfusion procedure patients with CHC and cardiac power less than 1.0 had highly mortality.
