Background Contemporary data on patients with heart failure (HF) in Saudi Arabia is limited. Methods This was a retrospective study of patients who were followed in the HF Clinic at our center after January 1, 2022. The study end date was August 31, 2023. Patients who were alive and followed for <6 months were excluded. We reported the clinical characteristics, utilization of established therapies for HF, proportion of potential candidates for ancillary HF treatments, and rates of HF events and mortality. Results A total of 202 patients met the study criteria. The mean age was 56.0 ± 15.2 years. The median follow-up from the initial visit to the study end date was 47 months (interquartile range {IQR}: 29-58 months). Coronary artery disease (CAD) was the cause of HF in 85 (42%) patients. At their latest visit, 103 (51%) patients had diabetes, 82 (41%) were obese, and 134 (66%) received quadruple therapy. Iron deficiency was present in 143 (71%) patients during follow-up. At their latest visit, moderate-to-severe or severe functional mitral regurgitation (MR) and hyperkalemia were present in 15 (7%) and 20 (10%) patients, respectively. The combined annual rate of HF hospitalization and emergency visits for HF was 20%. At least one hospitalization for HF within a year before the study end date occurred in 19 (9%) patients. The annual all-cause mortality was 1.8%. Conclusion This contemporary cohort of outpatients with HF was relatively young and had a high prevalence of diabetes, obesity, and iron deficiency. An estimate of potential candidates for iron replacement, transcatheter repair of the mitral valve, novel potassium binders, and the implantation of the pulmonary artery pressure monitor was among the first reported regionally. All-cause mortality was low, yet the burden of HF-related events was significant.
