Impact of Different Types of Statins on Clinical Outcomes in Patients Hospitalized for Ischemic Heart Failure

Introduction: The effect of statins on risk of heart failure (HF) hospitalization and lethal outcome remains dubious. Aim: To investigate whether statin therapy improves clinical outcomes in patients hospitalized for ischemic heart failure (HF), to compare the efficacy of lipophilic and hydrophilic statins and to investigate which statin subtype provides better survival and other outcome benefits. Material and Methods: Total amount of 155 patients in the study were admitted to the Clinic for Cardiology, Rheumatology and Vascular diseases in Clinical Center University of Sarajevo in the period from January 2014- December 2017. Inclusion criteria was HF caused by ischemic coronary artery disease upon admission. For each patient the following data were obtained: gender, age, comorbidities and medications on discharge. New York Heart Association (NYHA) class for heart failure was determined by physician evaluation and left ventricle ejection fraction (LVEF) was determined by echocardiography. The patients were followed for a period of two years. Outcome points were: rehospitalization, in-hospital death, mortality after 6 months, 1 year and 2 years. All-cause mortality included cardiovascular events or worsening heart failure. Results: Overall, 58.9% of HF patients received statin therapy, with 33.9% patients receiving atorvastatin and 25.0% rosuvastatin therapy. The most frequent rehospitalization was in patients without statin therapy (66.7%), followed by patients on rosuvastatin (64.1%), and atorvastatin (13.2%), with statistically significant difference p = 0.001 between the groups. Mortality after 6 months, 1 year and 2 years was the most frequent in patients without statin therapy with a statistically significant difference (p = 0.001). Progression of HF accounted for 31.7% of mortality in patients without statin therapy, 12.8% in patients on rosuvastatin therapy and 3.8% in patients on atorvastatin therapy (p = 0.004). Conclusion: Lipophilic statin therapy is associated with substantially better long-term outcomes in patients with HF.
