Objective
We aimed to investigate both the impact of COVID-19 pandemic on ST-segment elevation myocardial infarction (STEMI) admission, and demographic, angiographic, procedural characteristics, and in-hospital clinical outcomes of patients with COVID-19 positive STEMI in Turkey.
Methods
This was a multi-center and cross-sectional observational study. The study population included 1788 STEMI patients from 15 centers in Turkey. The patients were divided into two groups: COVID-19 era (March 11st–May 15st, 2020; n = 733) or pre- COVID-19 era group (March 11st–May 15st, 2019; n = 1055). Also, the patients in COVID-19 era were grouped as COVID-19 positive (n = 65) or negative (n = 668).
Results
There was a 30.5% drop in STEMI admission during COVID-19 era in comparison to pre-COVID-19 era. The patients admitted to the medical centers during COVID-19 era had a longer symptom-to-first medical contact time [120 (75–240) vs. 100 (60–180) minutes, p < 0.001]. COVID-19 positive STEMI patients had higher thrombus grade and lower left ventricular ejection fraction compared to COVID-19 negative patients. COVID-19 positive patients had higher mortality (28% vs. 6%, p < 0.001) and cardiogenic shock (20% vs. 7%, p < 0.001) rates compared with those without COVID-19. Matching based on propensity scores showed higher mortality and high thrombus grade in STEMI patients who were infected by SARS-COV-2 (each p < 0.05).
Conclusions
We detected significantly lower STEMI hospitalization rates and significant delay in duration of symptom onset to first medical contact in the context of Turkey during the COVID-19 outbreak. Moreover, high thrombus grade and mortality were more common in COVID-19 positive STEMI patients.

Cardiovascular disease is the most common cause of death in adult population in the world. The disease includes numerous problems, many of which are related to a process called atherosclerosis. Atherosclerosis is a condition that develops when a substance called plaque builds up in the walls of the arteries. This plaque narrows the arteries, making it harder for blood to flow through. If a blood clot forms, it can stop the blood flow. This can cause a heart attack or stroke. There are many risk factors associated with cardio vascular disease (CVD). While some risk factors cannot be changed, such as family history, some of them can be modified with treatment such as abnormal blood lipid and sugar levels, obesity, smoking, and high blood pressure. Research makes it clear that abnormal blood lipid (fat) levels have a strong correlation with the risk of coronary artery disease, heart attack and coronary death. Cholesterol plays detrimental roles in the pathogenesis of atherosclerosis and CVD. In this chapter, we aim to summarize the relationship between blood cholesterol levels and CVD.
Objective: To evaluate the efficacy of the monocyte/lymphocyte, platelet/lymphocyte, and HDL/LDL ratios as markers of the severity of coronary artery ectasia(CE).
Objective: Bleeding is one of the most important causes of mortality in patients with acute coronary syndrome (ACS). This study therefore aimed to investigate bleeding risk in patients with ACS who were scheduled to receive dual antiplatelet therapy (DAPT) in Turkey. Methods: This was a multicentre, observational, cross-sectional cohort study. The study population included 963 patients with ACS from 12 centres in Turkey. We used the Predicting Bleeding Complication in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT) score to predict the bleeding risk for all the patients. The patients were divided into high (≥25) or low (˂25) bleeding risk groups based on their PRECISE-DAPT scores. Results: The mean PRECISE-DAPT score was 21.9. Overall, 32.2% of the patients had high PRECISE-DAPT scores (≥25). Compared with the male patients, the female patients had higher PRECISE-DAPT scores (28.2 ± 15.7 vs 18.4 ± 13.6, P ˂ .001). Among the females, the rate of patients with a PRECISE-DAPT score ≥25 was 53%, while among the male patients, the score occurred at a rate of 22%. The female patients had lower haemoglobin (Hb) levels than the male patients (12.1 ± 1.7 vs 13.8 ± 1.9, P ˂ .001) and lower creatinine clearance (70.7 ± 27.5 vs 88.7 ± 26.3, P ˂ .001). The in-hospital bleeding rates were higher among the patients with high PRECISE-DAPT scores than among those who did not have high scores. Furthermore, the patients with high PRECISE-DAPT scores had a higher in-hospital mortality rate compared with those with low PRECISE-DAPT scores (1% vs 0%, P = .11). Conclusions: The mean PRECISE-DAPT score was high among the patients with ACS in this study, indicating that the bleeding tendency was high. This study showed 2 of 11 | AVCI et Al.
