The Coronavirus disease 2019 (COVID-19) pandemic has significantly affected the global health care system worldwide. The first COVID 19 case in Bahrain was detected on 24 February for a citizen travelling from Iran. The magnitude of the effect of COVID on the health care systems is unpredictable. However, the COVID national team task force made significant preparations to limit the spread of this virus and flatten the curve of the pandemic locally.
The Coronavirus disease 2019 (COVID-19) pandemic has significantly affected the global health care system worldwide. The first COVID 19 case in Bahrain was detected on 24 February for a citizen travelling from Iran. The magnitude of the effect of COVID on the health care systems is unpredictable. However, the COVID national team task force made significant preparations to limit the spread of this virus and flatten the curve of the pandemic locally. In Bahrain, the only cardiac center performing percutaneous and surgical cardiac interventions is Sh Mohammed bin Khalifa Cardiac Center (MKCC). This center receives direct admissions through emergency medical department (EMD) as well other cardiology referring hospitals.
Protocol and Methods:
In attempt to preserve resources, including personal protection equipment (PPE) and direct the work force to COVID centers. Certain protocols were adopted to maintain safe environment for patients and health care workers in the hospital. Elective cardiac procedures, including coronary angiography and percutaneous coronary intervention (PCI) for stable coronary artery disease were deferred (1). Thrombolysis with metalyse becomes the first line therapy for ST elevation Myocardial infarction (STEMI) unless contraindicated. Low grace score acute coronary syndromes (ACS) were treated with a conservative approach. If medical therapy failed, the patient was taken to the cardiac catheterization laboratory after ascertaining his/her COVID status. Cardiac catheterization laboratories were separately labelled as COVID and Non COVID labs with high-efficiency particulate air (HEPA) filter.
Preliminary data from different countries suggested a reduction in STEMI presentations at the inception of the COVID-19 pandemic2-3However, there is no such data representative of the gulf region. Moreover, it remains to be determined what effect COVID-19 has had on total cardiovascular admissions and the management of STEMI. Data on COVID-19 cases and cardiac admissions was collected retrospectively between 5 February 2020 and 1 May 2020. The COVID19 restrictions were started in the cardiac Centre on March 19. Following the restrictions, the total number of admissions reduced from 375 to 79, out of which 29 were ST elevation and 36 were non ST elevation myocardial infarction (NSTEMI). (Corresponding to a reduction of 79% in total cardiac medical admissions, 57% in STEMI and 60% in NSTEMI from the pre-COVID restrictions). (Figure 1a) While the number of total admissions during the COVID era reduced given the protocol adapted and the increasing number of daily COVID cases detected (Figure 1b), the reduction in numbers of STEMI patients remain a mystery(Figure 1c). Our results are in line with a recently published analysis from STEMI activations for 9 high-volume US centers [3]. The kingdom of Bahrain has not exercised a complete lockdown throughout the COVID19 pandemic, however public health measures like school closure, social distancing, public education and extensive testing were taken. The change in public behavior and the reluctance to present to hospital in fear of contacting the virus may explain reductions in STEMI cases. The number of (primary percutaneous coronary intervention) PPCI decreased by 90% during COVID-19 pandemic (Figure 1d). This has led to other tertiary care hospitals to manage STEMI cases by thrombolysis without referring to the Cardiac Centre, which might be a further reason to the decrease in STEMI admissions at the Cardiac Centre.
The data presented has some limitations. This is a retrospective single center study, reporting the initial few weeks before and after the pandemic first hit the Kingdom of Bahrain. Such initial measures taken to limit the virus spread may not be necessary in the future when experience is developed in dealing with COVID19. A balanced approach between measures to limit COVID19 spread, protect the healthcare workers and provide efficient services in managing cardiovascular diseases is essential. Therefore, modification to guidelines in management of STEMI in the COVID-19 era may evolve. Further follow up of the cases managed with current COVID-19 protocols is interesting. Modification to this protocol may help to set up a proper module for future pandemics.
