Hypertension encompasses a preventable risk factor associated with a significant global burden of cardiovascular disease (CVD) and premature death. Its prevalence is rising worldwide due to population aging, unbalanced diets, and sedentary, especially in low- and middle-income countries. Prevalence data in Brazil vary according to the database. However, about 30% of adults present blood pressure of 140/90 mmHg or more, with CVD representing 22.6% premature passing. This link between hypertension and CVDs-related deaths highlights the relevance of blood pressure control.

In 2021, the World Health Organization elaborated evidence-based guidance for the pharmacological treatment of nonpregnant adults with an accurate diagnosis of hypertension who have already received counseling for lifestyle modification. It is crucial to set blood pressure threshold to pharmacological therapy beginning and treatment targets. In addition, the determination of follow-up visits to adjust monotherapy or dual therapy embracing single or dual pill combination medications is mandatory. Comorbidities, unwanted effects, cost, and acceptability must also be evaluated. In 2020, the Brazilian Society of Cardiology also published decision and therapeutic goals for hypertension management.

Abstract

Background

Heart failure is an important cause of morbidity and mortality in children.

Objective

To determine the clinical characteristics of children with acute heart failure syndrome in the emergency ward of River state university teaching hospital, Nigeria and identify factors associated with poor outcomes.

Methods

This was an 18month retrospective review of the acute heart failure register. Poor outcome measures were defined as the persistence of heart failure after 4 days on admission or death.

Results

Ninety-two (4.1%) of 2,244 children admitted were in heart failure, Non-cardiac disorders [bronchopneumonia 32(36%), sepsis 21(24%), severe malaria 10(11%), sickle cell anaemia 8(9%) and tuberculosis 3(3%)] contributed to 74(83%) while congenital heart disease(CHD) was 15(17%). Seventy-four (83%) were discharged, 10(11%) died and 4(5%) left against medical advice. The median time to resolution of heart failure was significantly 24 hours longer for malnourished children than those with normal-nutritional status, 72Vs48hrs, log rank:0.001. Those with modified Ross score of >7 and sepsis were more likely to die, OR,8.8(95% CI,1.2 to 72.5,p = 0.02) and 3.9(95% CI,1.01 to 15.2;p =0.04). Age <2yrs(OR,3.1,CI,1.2 to 8.5,p = 0.02), and CHD (OR 3.6,95% CI,1.1 to 12,P=0.02) were associated with a higher likelihood of having a poor outcome. Each unit increase in weight for age Z score of 1, decreased the odds of having a poor outcome, OR,0.77 (95% CI,0.63 to 0.95)p=0.016.

Conclusion

Heart failure in our setting is predominantly caused by non-cardiac disorders. Modified Ross score of >7 and sepsis are risk factors for mortality in children with heart failure. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0
