ABSTRACT
Background: COVID-19 is a pandemic affecting 185 countries, including Indonesia. Cardiovascular diseases (CVD) in COVID-19 patients were linked to worse clinical outcomes. However, the association remained inconclusive due to limited data in Indonesia. This study aimed to determine the association between CVD in COVID-19 pneumonia patients with its clinical outcomes. Methods: This retrospective cohort study was conducted in four Indonesian hospitals, enrolling 584 adult COVID-19 pneumonia patients from September 2020 to July 2021. Patients were categorized into two groups: non-CVD and CVD [hypertension, coronary artery disease (CAD), chronic heart failure (CHF), hypertensive heart disease (HHD), arrhythmia, cardiomegaly, left ventricular hypertrophy (LVH), mitral regurgitation (MR), and myocardial injury (MI)]. Clinical outcomes include in-hospital mortality, intensive care unit admission, ventilator use, earlier death, and prolonged hospital stay. Mann-Whitney test was used for analysis. Results: The most common CVD was hypertension (48.1%), followed by MI (10.6%), CAD (9.2%), CHF (6.8%), HHD (3.1%), arrhythmia (1.7%), and others (0.7%). The in-hospital mortality rate was 24%, and patients were hospitalized for a median of 12 days. MI was the only CVD that increased in-hospital mortality (RR 2.105). It was also significantly increased in patients with diabetes mellitus (RR 1.475) and chronic kidney disease (RR 2.079). Meanwhile, prolonged hospital stay was associated with any CVD (RR 1.553), hypertension (RR 1.511), MI (RR 1.969), CHF (RR 1.595), diabetes mellitus (RR 1.359), and cerebrovascular disease (RR 2.203). Conclusion: COVID-19 pneumonia in patients with CVD, specifically MI and hypertension, worsens the COVID-19 clinical outcomes.
ABSTRACT
OBJECTIVE: A novel antithrombotic agent, lumbrokinase, was evaluated in this pilot study for its efficacy in the treatment of symptomatic stable angina. DESIGN: This was a single-armed cohort study. SETTINGS: The study was conducted at the National Cardiovascular Center, Harapan Kita, Jakarta, Indonesia. SUBJECTS: The study comprised 10 patients who had coronary artery disease and stable angina and who consented to the trial. INTERVENTION: Patients were treated with oral lumbrokinase for 30 consecutive days in addition to their standard medical therapy. OUTCOME MEASURES: Stress technetium-99m sestamibi myocardial perfusion imaging (MPI) was performed before and at the conclusion of the active treatment period. The degree and extent of inducible ischemia observed on the myocardial perfusion images were evaluated using the previously validated semiquantitative indices (Summed Stress Score and Summed Difference Score). RESULTS: Following active treatment, the mean Summed Stress Score and Summed Difference Score deceased by 39% and 37%, respectively. The anginal symptom was ameliorated in 6 of 10 patients. No adverse reaction including major or minor bleeding was observed. CONCLUSIONS: This paper represents the first description of the use of oral lumbrokinase in the treatment of chronic coronary artery disease with objective assessment using MPI. Oral lumbrokinase improves regional myocardial perfusion in patients with stable angina.
