Continuous Decline in Myocardial Infarction and Heart Failure Hospitalizations during the First 12 Months of the COVID-19 Pandemic in Israel

Epidemiological, clinical, and economic burden of myocardial infarction patients in Iran during the COVID-19 pandemic

Background

To define changes in AMI case rates, patient demographics, cardiovascular comorbidities, treatment approaches, in-hospital outcomes, and the economic burden of COVID-19 during the pandemic.

Methods

We conducted a multicenter, observational survey with selected hospitals from three medical universities in Tehran city. A data collection tool consisting of three parts. The first part included socio-demographic information, and the second part included clinical information, major complications, and in-hospital mortality. Finally, the third part was related to the direct medical costs generated by AMI in COVID-19 and non-COVID-19 patients. The study cohort comprised 4,560 hospitalizations for AMI (2,935 for STEMI [64%] and 1,625 for NSTEMI [36%]).

Results

Of those hospitalized for AMI, 1,864 (76.6 %) and 1,659 (78 %) were male before the COVID-19 outbreak and during the COVID-19 era, respectively. The length of stay (LOS), was significantly lower during the COVID-19 pandemic era (4.27 ± 3.63 vs 5.24 ± 5.17, p = 0.00). Results showed that there were no significant differences in terms of patient risk factors across periods. A total of 2,126 AMIs were registered during the COVID-19 era, with a 12.65 % reduction (95 % CI 1.5-25.1) compared with the equivalent time in 2019 (P = 0.179). The risk of in-hospital mortality rate for AMI patients increased from 4.9 % in 2019 to 7.0 % in the COVID-19 era (OR = 1.42; 95 % CI 1.11-1.82; P = 0.004). Major complications were registered in 9.7 % of cases in 2020, which is higher than the rate of 6.6 % reported in 2019 (OR = 1.46, 95 % CI 1.11-1.82; P = 0.000). Total costs in hospitalized AMI-COVID patients averaged $188 more than in AMI patients (P = 0.020).

Conclusion

This cross-sectional study found important changes in AMI hospitalization rates, worse outcomes, and higher costs during the COVID-19 periods. Future studies are recommended to examine the long-term outcomes of hospitalized AMI patients during the COVID-19 era.

Impact of COVID-19 pandemic on catheter ablation in China: A spatiotemporal analysis

Background

The COVID-19 pandemic has significantly impacted routine cardiovascular health assessments and services. We aim to depict the temporal trend of catheter ablation (CA) and provide experience in dealing with the negative impact of the COVID-19 pandemic.

Methods

Data on CA between January 2019, and December 2021, were extracted from the National Center for Cardiovascular Quality Improvement platform. CA alterations from 2019 to 2021 were assessed with a generalized estimation equation.

Results

A total of 347,924 patients undergoing CA were included in the final analysis. The CA decreased remarkably from 122,839 in 2019 to 100,019 (-18.58%, 95% CI: -33.40% to -3.75%, p = 0.02) in 2020, and increased slightly to 125,006 (1.81%, 95% CI: -7.01% to 3.38%, p = 0.49) in 2021. The CA experienced the maximal reduction in February 2020 (-88.78%) corresponding with the peak of monthly new COVID-19 cases and decreased by 54.32% (95%CI: -71.27% to -37.37%, p < 0.001) during the 3-month lockdown and increased firstly in June 2020 relative to 2019. Since then, the CA in 2020 remained unchanged relative to 2019 (-0.06%, 95% CI: -7.01% to 3.38%, p = 0.98). Notably, the recovery of CA in 2021 to pre-COVID-19 levels was mainly driven by the growth of CA in secondary hospitals. Although there is a slight increase (2167) in CA in 2021 relative to 2019, both the absolute number and proportion of CA in the top 50 hospitals nationwide [53,887 (43.09%) vs. 63,811 (51.95%), p < 0.001] and top three hospitals in each province [66,152 (52.73%) vs. 72,392 (59.28%), p < 0.001] still declined significantly.

Conclusions

The CA experienced a substantial decline during the early phase of the COVID-19 pandemic, and then gradually returned to pre-COVID-19 levels. Notably, the growth of CA in secondary hospitals plays an important role in the overall resumption, which implies that systematic guidance of secondary hospitals with CA experience may aid in mitigating the negative impact of the COVID-19 pandemic.

Demographic Trends and Changes in the Pre- and In-Hospital Medical Management of Acute Myocardial Infarction During the First 12 Months of the COVID-19 Pandemic in Mie Prefecture ― Report From the Mie ACS Registry ―

Background: Even though hospital admissions for acute myocardial infarction (AMI) decreased globally during the COVID-19 pandemic in early 2020, limited information is available on subsequent demographic trends in the number of cases and management of AMI through the first 12 months of the COVID-19 pandemic.

Methods and Results: We assessed demographic trends, patient characteristics, and AMI outcomes (n=730) during the first 12 months of the COVID-19 pandemic and compared them with corresponding months during the control period (February 2016–January 2020; n=2,742) using data from the Mie ACS Registry. Although a 25.8% reduction in hospitalizations for AMI was observed in the 3 months following the declaration of a state of emergency (47.7 vs. 64.3/month; P=0.002), the total number of AMI patients was similar between the 12-month COVID-19 and control periods (60.8 vs. 57.2/month; P=0.58). The number of patients requiring direct ambulance transport was lower in the first half of the COVID-19 than control period (44.4% vs. 51.5; P=0.028). In-hospital mortality was higher in the second half of the COVID-19 than control period (8.9% vs. 5.8%; P=0.032).

Conclusions: Through the first 12 months of the COVID-19 pandemic, the number of AMI cases was similar to that in previous years. The COVID-19 pandemic changed the behavior of AMI patients and both pre- and in-hospital medical management, which significantly affected the severity and prognosis of AMI.

Trends in the Volume and Types of Primary Care Visits during the Two Years of the COVID-19 Pandemic in Israel

BACKGROUND

The outbreak of the COVID-19 pandemic led to a decrease in primary health care in-person visits and a simultaneous increase in virtual encounters.

OBJECTIVE

To quantify the change in the total volume of primary care visits and mix of visit types during the two years of the pandemic in Israel.

DESIGN

Cross-sectional study.

PARTICIPANTS

All primary care visits by members of the largest healthcare organization in Israel, during three one-year periods: the pre-COVID-19 year (March 2019-February 2020), the first year of COVID-19 (March 2020-February 2021), and the second year of COVID-19 (March 2021-February 2022).

MAIN MEASURES

Total volume of primary care visits and mix of visit types.

RESULTS

More than 112 million primary care visits were included in the study. The total visit rate per 1000 members did not change significantly between the pre-COVID year (19) and the first COVID year (19.8), but was 21% higher in the second COVID-19 year (23). The rate of in-person visits per 1000 members decreased from 12.0 in the pre-COVID year to 7.7 in the first COVID year and then increased to 9.6 in the second. The rate of phone visits and asynchronous communication increased from 0.7 and 6.3, respectively, in the pre-COVID year, to 4.1 and 8, respectively, in the first COVID year, and remained unchanged in the second. There was substantial variation across age groups and sectors in the adoption of virtual platforms.

CONCLUSIONS

The rapid introduction of virtual encounters in primary care tended to displace in-person visits in the first year of the pandemic, but they appear to have been additive in the second. This transition should be monitored, with the goal of ensuring appropriate planning efforts and resource allocation to deal with the potential added burden on medical staff. Efforts should be invested in encouraging the use of virtual platforms in patient groups that currently underutilize it, such as minorities.

Ongoing COVID-19 Pandemic Effects on Admissions and In-Hospital Outcomes in Patients With ST-Elevation Myocardial Infarction (STEMI): An Albanian Observational Study

Background Multiple studies conducted worldwide and in Albania documented an important reduction of acute ST-elevation myocardial infarction (STEMI) admissions during the Coronavirus Disease 19 (COVID-19) pandemic. There are few studies regarding STEMI admissions and outcomes during the ongoing pandemic after the initial lockdown. We aimed to study STEMI admissions and in-hospital outcomes after the COVID-19 lockdown period. Methods A retrospective single-center study was conducted, collecting data for all consecutive STEMI admissions from March 9th, (the first COVID-19 case) until April 30th, the corresponding period of 2020 total lockdown, for years 2019 and 2021. The control period was considered the year 2019 [pre-pandemic (PP)] and the study period was in 2021 [ongoing pandemic (OP)]. The incidence rate ratio (IRR) 95% confidence interval (CI) was used to compare all-STEMI admissions, invasive procedures, and risk ratio (RR) 95% CI to compare the mortality and complications rate between the study and control period. Results The study included 217 STEMI patients admitted in 2019, and 234 patients during the 2021 period. The overall-STEMI admissions IRR is in a similar range during the 2021 OP compared to the 2019 PP period IRR=1.07 (95%CI 0.90-1.28). Similar invasive procedures were observed during OP compared to PP period, respectively for coronary-angiography IRR= 1.07; (0.87-1.31), for all-PCI [1.12 (0.92-1.35)], and primary percutaneous coronary interventions (PCI) [1.09 (0.89-1.34)]. The STEMI death rate during OP compared to PP period was similar (7.3 vs. 7.4%), RR=1.01 (0.53-1.96), and a non-significant lower primary-PCI-death rate (4.0 vs 4.8%), RR= 0.83 (0.30-2.3)]. Conclusions After the initial reduction of admissions and invasive procedures in STEMI patients during the 2020 lockdown period and the increase of all-STEMI mortality, the number of hospitalizations, invasive procedures, and mortality returned to a similar range during OP compared to the PP period despite a highly incident ongoing COVID-19 pandemic.
