Summary

Coronavirus disease of 2019 (COVID-19) affected the health care systems all around the world. The collateral damage of the pandemic on the cardiovascular (CV) care and CV mortality has been noticed and reported early. In Lithuania, first quarantine measurements were introduced on 16th March and lifted on 16th June of 2020, limiting contact appointments to urgent care only. This led to a substantial proportion of routine cardiovascular appointments, diagnostic and therapeutic procedures being cancelled and greatly limited the availability of cardiovascular care. The prognostic impact of this has not been appropriately analysed. Also, comprehensive analyses of the changes in national CV services, including outpatient care and hospitalisations and CV mortality, during different periods of the pandemic (during first and second waves and in between) are scarce. The objectives of this population-based study were: (1) to assess the impact of the COVID-19 pandemic on CV care (2) to compare rates of outpatient care visits and hospitalisations of cardiovascular patients in different periods of 2019 and 2020 (3) to compare the rates of CV mortality in Lithuania in different periods of 2019 and 2020 (4) to investigate sex and age differences in CV care and CV mortality

Detailed description

COVID-19 pandemic has greatly affected the world and changed health care in almost every country. During the spring of 2020, first pandemic wave was of different scale in different countries. In countries affected by the virus the most, a majority of the studies focused on the direct impact of COVID-19 on community health. It was noticed promptly that the novel virus is especially high-risk for patients with cardiovascular comorbidities. Furthermore, the collateral damage of COVID-19 pandemic on the provision of cardiovascular (CV) care and cardiovascular mortality was also reported early in several nationwide and selected cohort studies. The research was mostly focused on acute cardiovascular conditions; changes in hospital admissions and early mortality after myocardial infarction were also often analysed. Meanwhile, a substantial proportion of routine appointments, diagnostic and therapeutic procedures was cancelled. Data on the changes in total national CV services, including out- and in-patient health care facilities, acute and chronic conditions, during the outbreak, between the two pandemic waves and onwards are scarce. First case of COVID-19 in Lithuania was confirmed on 28th February 2020. First nationwide quarantine was introduced by Lithuanian government on 16th March and ended on 16th June. In that period, although Lithuania was reported among the least affected countries according to World Health Organization - 1 773 COVID-19 cases were recorded and 86 patients (of whom 10 patients died from other causes after testing positive for SARS-CoV-2) had died before the end of quarantine, Lithuanian government limited contact appointments to urgent conditions only. The utmost efforts to provide triage, follow-up care by telephone call and e-prescriptions were recommended. This greatly affected availability of cardiovascular care. The second pandemic wave in Lithuania was substantially more severe. Consequently, the second nationwide quarantine was implemented on 7th November, 2020. Contact appointments were not limited by the government; however, the scope of CV care was again negatively affected, mostly by the strained health care system. We analysed the indirect impact of the COVID-19 pandemic in a country, which was hit by two very different pandemic waves. The objectives of this population-based study were: (1) to assess the impact of the COVID-19 pandemic on CV care (2) to compare rates of outpatient care visits and hospitalisations of cardiovascular patients in different periods of 2019 and 2020 (3) to compare the rates of CV mortality in Lithuania in different periods of 2019 and 2020 (4) to investigate sex and age differences in CV care and CV mortality

Type	Name	Description
OTHER	Data collection on outpatient care	Outpatient data from 1 January to 30 November of the analysed year were obtained from National Health Insurance Fund under the Ministry of Health. Outpatient data related to cardiovascular diseases (CVD) were collected as described: 1. data on visits were collected using ICD-10 codes I00-I99 and other CVD related codes (e.g., certain Z, Q codes, J81.0, R57.0) 2. data were collected from CVD prevention program 3. data on interventional cardiology were collected from day care facility regardless of the diagnosis. Date of the visit, patient age, sex and municipality, service level (primary, secondary or tertiary), type of service and main diagnosis were recorded.
OTHER	Data collection on hospitalisation	Hospitalisation data from 1 January to 30 November of the analysed year were obtained from National Health Insurance Fund under the Ministry of Health. Data on hospitalisation were collected if any of the diagnoses (principal or secondary) were in I00-I99 range. Hospitalisation data covered hospitalisation date, patient age, sex, municipality and outcome. Data on cardiovascular procedures performed during hospitalisations included date of the procedure and ACHI (Australian Classification of Health Interventions) code.
OTHER	Data collection on cardiovascular mortality	Data on cardiovascular mortality were obtained from death certificates provided by Causes of Death Registry from Institute of Hygiene and covered the period from 1 January to 31 December of the analysed year. Death certificates were included in the study when cause of death was adjudicated to be in I00-I99 range. Date and place of death (hospital, home, other or unspecified), patient age and sex were recorded.
OTHER	Data collection of patients presenting to the tertiary care centre with acute coronary syndrome	Demographic, clinical and percutaneous coronary intervention (PCI) related data were collected from 1st March to 30th June of the analysed year. The timing of the chest pain onset, call for medical help, first medical contact (FMC), arrival to PCI centre, and PCI procedure were analysed.
