COVID-19 and ischemic heart disease emergencies: What cardiac surgery should expect?

Impact of coronavirus disease on acute appendicitis cases

BACKGROUND

Disease profiles have changed in the COVID-19 pandemic. In this study, we aimed to compare acute appendicitis cases before and during the COVID-19 pandemic.

METHODS

A total of 130 patients were diagnosed with AA and operated between the days of first COVID-19 case on March 11, 2020, and May 11, 2020, and the same period of the previous year. Data of the patients were extracted from electronic archive of the hospital. Those patients were stratified into two groups; pandemic group and pre-pandemic group. The pandemic group comprised 46 patients and the pre-pandemic group, 84 patients. The two groups were compared in terms of age, gender, duration of symptoms, length of hospital stay, white blood cell count, C-reactive protein levels, and post-operative complications.

RESULTS

The median days passed from onset of abdominal pain to submission were 6.5 days in the pandemic period. However, it was 3 days in the pre-pandemic group (p<0.001). Other parameters were not statistically different between the groups (p>0.05).

CONCLUSION

During the COVID-19 pandemic period, delay in hospital submissions has attracted attention. However, delayed treatment did not reflect to the clinic as more severe disease.

Rural and Female Patients with Old Myocardial Infarction Lacked Knowledge and Preventive Measures During the Beginning of the COVID-19 Epidemic in Chongqing, Southwest China

BACKGROUND Coronavirus disease 2019 (COVID-19) has emerged as a global threat. This study was performed to gain an understanding of COVID-19-related knowledge, attitudes, and practices among susceptible individuals. MATERIAL AND METHODS Patients who had been diagnosed with old myocardial infarction were followed up via telephone survey based on an established follow-up system at the beginning of the COVID-19 outbreak (January 2020) in Chongqing, Southwest China. RESULTS A total of 631 eligible patients participated in this survey, and 40.6% of the rural respondents did not know the transmission routes of SARS-CoV-2, which was higher than the proportion of urban respondents (40.6% vs 31.0). Rural residents had a lower rate of adopting preventive measures than urban residents, such as wearing masks (76.7% vs 90.1%), avoiding meetings and gatherings (58.6% vs 68.5%), and hand washing (56.0% vs 63.8%). A higher percentage of women than men did not take any preventive measures (11.3% vs 7.6%), while a lower percentage of women than men wore masks (77.7% vs 84.5%). Multiple logistic regression revealed that rural patients were more likely to lack knowledge about transmission (odds ratio (OR): 1.51). Rural patients had an increased risk of failing to implement protective measures. CONCLUSIONS Female and rural populations lacked knowledge and failed to adopt protective measures during the beginning of the COVID-19 epidemic. Therefore, these populations may benefit from health education campaigns and policies.

Acute Brain Ischemia, Infarction and Hemorrhage in Subjects Dying with or Without Autopsy-Proven Acute Pneumonia

Stroke is one of the most serious complications of Covid-19 disease but it is still unclear whether stroke is more common with Covid-19 pneumonia as compared to non-Covid-19 pneumonia. We investigated the concurrence rate of autopsy-confirmed acute brain ischemia, acute brain infarction and acute brain hemorrhage with autopsy-proven acute non-Covid pneumonia in consecutive autopsies in the Arizona Study of Aging and Neurodegenerative Disorders (AZSAND), a longitudinal clinicopathological study of normal aging and neurodegenerative diseases. Of 691 subjects with a mean age of 83.4 years, acute pneumonia was histopathologically diagnosed in 343 (49.6%); the concurrence rates for histopathologically-confirmed acute ischemia, acute infarction or subacute infarction was 14% and did not differ between pneumonia and non-pneumonia groups while the rates of acute brain hemorrhage were 1.4% and 2.0% of those with or without acute pneumonia, respectively. In comparison, in reviews of Covid-19 publications, reported clinically-determined rates of acute brain infarction range from 0.5% to 20% while rates of acute brain hemorrhage range from 0.13% to 2%. In reviews of Covid-19 autopsy studies, concurrence rates for both acute brain infarction and acute brain hemorrhage average about 10%. Covid-19 pneumonia and non-Covid-19 pneumonia may have similar risks tor concurrent acute brain infarction and acute brain hemorrhage when pneumonia is severe enough to cause death. Additionally, acute brain ischemia, infarction or hemorrhage may not be more common in subjects dying of acute pneumonia than in subjects dying without acute pneumonia.

Mechanical complications of myocardial infarction during COVID-19 pandemic: An Italian single-centre experience

COVID-19 pandemic triggered in many patients the fear to go to the emergency rooms in order to avoid a possible infection. This phenomenon caused a significant reduction in acute coronary syndrome-related interventional procedures with a subsequent increase in critical hospitalizations and post-infarction mechanical complications. A case series of cardiac ruptures during the COVID-19 lockdown and the surgical treatment of a huge post-ischemic cardiac pseudoaneurysm complicated by a “contained” free wall rupture are presented.
