Background
Infective endocarditis (IE) is a potentially fatal condition with high morbidity and mortality. This single center study was designed to assess the clinical presentation, causative organisms, antibiotic resistance, and clinical outcomes of IE in patients treated at a tertiary care cardiac center in Pakistan.
Methods
A retrospective observational study was conducted at a large tertiary care cardiology center in Peshawar, Pakistan from July 2021 to July 2023. Data was collected from hospital records, including demographic, clinical, and laboratory parameters. Statistical analysis was performed using Stata version 14.2.
Results
Among 84 patients, 41.7% were male with a mean population age of 49.17 ± 18.55 years, and an average BMI of 27.72 ± 4.37 kg/m 2 . Hypertension was the most common comorbidity, found in 47.6% patients, followed by diabetes in 36.9% patients. Streptococcus Viridans (25%) was the most common organism isolated, followed closely by Staphylococcus aureus at 22.6%. Surprisingly, 32.1% of the patients had negative cultures. Antibiotic resistance was observed in 25/57 (43.9%) of culture positive cases, and Major Adverse Cardiovascular Events (MACE) occurred in 56%. Acute kidney injury was observed in 48.8% of the patients.
Conclusion
IE presents diverse etiologies and outcomes, necessitating targeted management strategies to reduce antibiotic resistance and improve outcomes in such a challenging subsets of patients.
