Adherence to Congestive Heart Failure Guidelines and Outcome in the Middle East

Adherence to Congestive Heart Failure with reduced Ejection Fraction (CHFrEF) guidelines is not easily attainable everywhere, particularly in countries with a high prevalence of low socioeconomic status, which includes many Middle Eastern countries. However, it is well-established that adherence to the guidelines is associated with lower mortality and morbidity rates.

Our objective is to investigate the adherence to the degree of treatment guideline in CHFrEF within a patient population in the Middle East and correlate the level of compliance both fully and partially with morbidity and mortality outcomes. Methods and Statistics: We conducted a retrospective study on patients with CHFrEF in the Middle East region who were maintained on Sacubitril/Valsartan for up to 4 years (190 patients). This study included follow-up assessments for morbidity and mortality rates and their correlation with the level of adherence to guidelines.

Statistical analysis was performed using IBM SPSS® 27th version. In both the partial adherence group and the full adherence group, there was a statistically significant improvement in NYHA (pretreatment and post-treatment) and Ejection fraction (pretreatment and posttreatment). This means that regardless of the level of adherence to the use of Sacubitril/Valsartan in CHFrEF, there was an overall improvement in the morbidity and mortality rates over the four years of follow-up.

While we fully support the idea of achieving full CHFrEF guideline adherence, we recognize the difficulty of this task. Nevertheless, this study reinforces the notion that any degree of adherence to guideline is correlated with better morbidity and mortality rates over a long-term follow-up.
