Clinical features, management, and short‐ and long‐term outcomes of patients with acute decompensated heart failure: phase I results of the HEARTS database

Abstract

Aims The HEart function Assessment Registry Trial in Saudi Arabia (HEARTS) is a national multicentre project, studying clinical features, management, short‐ and long‐term outcomes, and mortality predictors in patients admitted with acute decompensated heart failure (ADHF). Methods and results Our prospective registry enrolled 2610 ADHF patients admitted to 18 hospitals in Saudi Arabia between October 2009 and December 2010, and followed mortality rates until January 2013. The patients included 66% men and 85.5% Saudis, with a median age (interquartile range) of 61.4 (15) years; 64% had acute on chronic heart failure (HF), 64.1% diabetes mellitus, 70.6% hypertension, and 55.7% CAD. Exacerbating factors for hospital admission included acute coronary syndromes (37.8%), infections (20.6%), non‐compliance with low‐salt diet (25.2%), and non‐compliance with HF medications (20%). An LVEF <40% was found in 73%. In‐hospital use of evidence‐based medications was high. All‐cause cumulative mortality rates at 30 days, 6 months, 1 year, 2 years, and 3 years were 8.3, 13.7, 19.5, 23.5, and 24.3%, respectively. Important independent predictors of mortality were history of stroke, acute on chronic HF, systolic blood pressure <90 mmHg upon presentation, estimated glomerular filtration rate <60 mL/min, and haemoglobin <10 g/dL. Conclusion Patients with ADHF in Saudi Arabia presented at a younger age and had higher rates of CAD risk factors compared with those in developed countries. Most patients had reduced LV systolic function, mostly due to ischaemic aetiology, and had poor long‐term prognosis. These findings indicate a need for nationwide primary prevention and HF disease management programmes.

Gender differences in Egyptian patients hospitalized with heart failure: insights from the European Society of Cardiology Heart Failure Long‐Term Registry

“…7 El-Zanaty and Way 8 reported in a survey carried out in Egypt in 2008 that obesity in women increased directly with age, from a level of 10% among women aged 15-19 years to 65% or more among women in the 45-59 year age groups. Women presented with a higher admission SBP and resting heart rate.…”

Long-Term Mortality Rates in Acute De Novo Versus Acute-on-Chronic Heart Failure

“…22,23 The HEARTS also includes a quality improvement initiative that aims to identify ''knowledge-care'' gaps and potentially improve patient outcomes. In the present study, we describe the baseline clinical characteristics, management, short-and longterm mortality rates, and independent predictors of death in patients with de novo AHF and ACHF.…”

In‐hospital ventricular arrhythmia in heart failure patients: 7 year follow‐up of the multi‐centric HEARTS registry

“…18,19 The registry had enrolled 2610 patients admitted into the coronary care unit/intensive care unit or the wards, with acute decompensated HF whether de novo (no previous history of HF) or with acute/chronic HF. To stay brief, the Kingdom of Saudi Arabia is the largest country in the Arabian Peninsula, and it is the second largest producer of crude oil in the world with a gross domestic product per capita of 21 057.33 USD in 2017.…”
