Comparison of reorganized versus unaltered cardiology departments during the COVID-19 era: A subanalysis of the COV-HF-SIRIO 6 study.

BACKGROUND: Since the beginning of the coronavirus disease 2019 (COVID-19) pandemic, numerous cardiology departments were reorganized to provide care for COVID-19 patients. We aimed to compare the impact of the COVID-19 pandemic on hospital admissions and in-hospital mortality in reorganized vs. unaltered cardiology departments. METHODS: The present research is a subanalysis of a multicenter retrospective COV-HF-SIRIO 6 study that includes all patients (n = 101,433) hospitalized in 24 cardiology departments in Poland between January 1, 2019 and December 31, 2020, with a focus on patients with acute heart failure (AHF). RESULTS: Reduction of all-cause hospitalizations was 50.6% vs. 21.3% for reorganized vs. unaltered cardiology departments in 2020 vs. 2019, respectively (p < 0.0001). Considering AHF alone respective reductions by 46.5% and 15.2% were registered (p < 0.0001). A higher percentage of patients was brought in by ambulance to reorganized vs. unaltered cardiology departments (51.7% vs. 34.6%; p < 0.0001) alongside with a lower rate of self-referrals (45.7% vs. 58.4%; p < 0.0001). The rate of all-cause in-hospital mortality in AHF patients was higher in reorganized than unaltered cardiology departments (10.9% vs. 6.4%; p < 0.0001). After the exclusion of patients with concomitant COVID-19, the mortality rates did not differ significantly (6.9% vs. 6.4%; p = 0.55). CONCLUSIONS: A greater reduction in hospital admissions in 2020 vs. 2019, higher rates of patients brought by ambulance together with lower rates of self-referrals and higher all-cause in-hospital mortality for AHF due to COVID-19 related deaths were observed in cardiology departments reorganized to provide care for COVID-19 patients vs. unaltered ones.

Impact of COVID-19 pandemic on acute heart failure admissions and mortality: a multicentre study (COV-HF-SIRIO 6 study).

AIMS: The coronavirus disease-2019 (COVID-19) pandemic has changed the landscape of medical care delivery worldwide. We aimed to assess the influence of COVID-19 pandemic on hospital admissions and in-hospital mortality rate in patients with acute heart failure (AHF) in a retrospective, multicentre study. METHODS AND RESULTS: From 1 January 2019 to 31 December 2020, a total of 101 433 patients were hospitalized in 24 Cardiology Departments in Poland. The number of patients admitted due to AHF decreased by 23.4% from 9853 in 2019 to 7546 in 2020 (P < 0.001). We noted a significant reduction of self-referrals in the times of COVID-19 pandemic accounting 27.8% (P < 0.001), with increased number of AHF patients brought by an ambulance by 15.9% (P < 0.001). The length of hospital stay was overall similar (7.7 ± 2.8 vs. 8.2 ± 3.7 days; P = not significant). The in-hospital all-cause mortality in AHF patients was 444 (5.2%) in 2019 vs. 406 (6.5%) in 2020 (P < 0.001). A total number of AHF patients with concomitant COVID-19 was 239 (3.2% of AHF patients hospitalized in 2020). The rate of in-hospital deaths in AHF patients with COVID-19 was extremely high accounting 31.4%, reaching up to 44.1% in the peak of the pandemic in November 2020. CONCLUSIONS: Our study indicates that the COVID-19 pandemic led to (i) reduced hospital admissions for AHF; (ii) decreased number of self-referred AHF patients and increased number of AHF patients brought by an ambulance; and (iii) increased in-hospital mortality for AHF with very high mortality rate for concomitant AHF and COVID-19.

Myocardial Infarction in Centenarians. Data from The Polish Registry of Acute Coronary Syndromes.

BACKGROUND: There are no data regarding the mortality rate, risks and benefits of particular reperfusion methods and pharmacological treatment complications in patients aged over 100 years with acute coronary syndromes. We sought to assess the treatment of myocardial infarction (MI) in patients older than 100 years and to determine prognostic factors for this group. METHODS: Among the 716,566 patients recorded between 2003 and 2018 in the Polish Registry of Acute Coronary Syndromes, 104 patients aged ≥100 with MI were included. The patients were categorized into two groups: group 1 received conservative treatment (64 patients), and group 2 received invasive strategy (40 patients). RESULTS: The frequencies of in-hospital mortality, MI and stroke were similar in both arms. No difference in the frequency of the combined endpoint (death, reinfarction, stroke) was noted. Invasive treatment was more advantageous for 12-month outcomes; 50 patients in group 1 (79%) and 23 patients in group 2 (57.50%) died (p = 0.017). The multivariate analysis identified the lower left ventricular ejection fraction (EF) (Hazard Ratio (HR) = 0.96; 95% Confidence Interval (CI): 0.94-0.99; p = 0.012), lack of coronary angiography (HR = 0.49; 95% CI: 0.24-0.99; p = 0.048) and cardiac arrest (HR = 4.61; 95% CI: 1.64-12.99; p = 0.0038) as predictors of 12-month mortality in this group. CONCLUSIONS: Invasive MI treatment may be beneficial for selected very old patients.

[Late stent thrombosis thirteen months after drug-eluting stent implantation]. / Zakrzepica w stencie trzynascie miesiecy po wszczepieniu stentu powlekanego lekiem antyproliferacyjnym.

We present a case of a very late stent thrombosis which occurred 13 months after drug-eluting stent (DES) implantation. The DES was off-label used in a high-risk patient and was followed by 12-month clopidogrel administration. One month after the drug discontinuation the stent thrombosis occurred, resulting in acute myocardial infarction. The patient was successfully treated with balloon coronary angioplasty and was advised to use clopidogrel indefinitely.

Left ventricular apical rupture caused by takotsubo cardiomyopathy--comprehensive pathological heart investigation.

An 81-year-old woman with emotionally-induced takotsubo cardiomyopathy developed a fatal left ventricular (LV) apical rupture. During the hospitalization persistent ST-segment elevation with no electrocardiographic time evolution was observed on the ECG, characteristic for takotsubo cardiomyopathy. Histopathologically, transmural myocardial necrosis with hemorrhage was found at the rupture site, but there were foci of coagulation and contraction band necrosis with mononuclear lymphocyte infiltrations in other heart regions, and the intensity and distribution of these pathological changes corresponded to the distribution of the LV contraction abnormalities seen on ventriculography. The article concludes that: the LV functional disorder in takotsubo cardiomyopathy may be caused by distracted foci of coagulation and contraction band necrosis in the myocardium; contraction band necrosis (a sign of catecholamine cardiotoxicity) may reflect the sympathetic hyperactivity in this disease; persistent myocardial damage expressed by persistent ST-segment elevation without an electrocardiographic time evolution should be carefully observed with sequential echocardiographic examinations because of the possibility of cardiac rupture.
