“…Despite several reports of special features and probable underlying coagulopathy in AIS with prior SARS-CoV-2 infection [ 2 , 4 , 6 , 7 , 8 , 9 , 10 ], similar reports are lacking in the literature regarding acute coronary syndrome and cardiovascular thromboembolic events. The majority of adverse outcomes among patients with stroke [ 39 , 40 ] or acute coronary syndrome [ 11 , 12 , 13 , 14 , 15 ] were related to the declining trend in seeking urgent care, hospitalization, and receiving guideline indicated measures. On the other hand, the meta-analyses of AIS infected patients presented a mean age of over 65 years and a high load of comorbidities [ 21 , 22 ].…”

“…A dramatic decline in the guideline-indicated care, hospitalization rate, and revascularization procedures are other possible factors attributing to adverse outcomes in patients with acute coronary syndrome [ 11 , 12 , 13 , 14 , 15 ]. Studies have failed to show any difference among cardiovascular patients in terms of age, sex, comorbidities, clinical presentation, and diagnosis pre- and post-pandemic era [ 14 , 16 ]. Similarly, a higher rate of coronary stent thrombosis in comparison with the pre-pandemic era [ 17 , 18 ] was reported among the patients with multiple comorbidities (about 44% with at least four vascular risk factors) and a median age of 65 years [ 18 ].…”

Background. SARS-CoV-2 infected patients are suggested to have a higher incidence of thrombotic events such as acute ischemic strokes (AIS). This study aimed at exploring vascular comorbidity patterns among SARS-CoV-2 infected patients with subsequent stroke. We also investigated whether the comorbidities and their frequencies under each subclass of TOAST criteria were similar to the AIS population studies prior to the pandemic. Methods. This is a report from the Multinational COVID-19 Stroke Study Group. We present an original dataset of SASR-CoV-2 infected patients who had a subsequent stroke recorded through our multicenter prospective study. In addition, we built a dataset of previously reported patients by conducting a systematic literature review. We demonstrated distinct subgroups by clinical risk scoring models and unsupervised machine learning algorithms, including hierarchical K-Means (ML-K) and Spectral clustering (ML-S). Results. This study included 323 AIS patients from 71 centers in 17 countries from the original dataset and 145 patients reported in the literature. The unsupervised clustering methods suggest a distinct cohort of patients (ML-K: 36% and ML-S: 42%) with no or few comorbidities. These patients were more than 6 years younger than other subgroups and more likely were men (ML-K: 59% and ML-S: 60%). The majority of patients in this subgroup suffered from an embolic-appearing stroke on imaging (ML-K: 83% and ML-S: 85%) and had about 50% risk of large vessel occlusions (ML-K: 50% and ML-S: 53%). In addition, there were two cohorts of patients with large-artery atherosclerosis (ML-K: 30% and ML-S: 43% of patients) and cardioembolic strokes (ML-K: 34% and ML-S: 15%) with consistent comorbidity and imaging patterns. Binominal logistic regression demonstrated that ischemic heart disease (odds ratio (OR), 4.9; 95% confidence interval (CI), 1.6–14.7), atrial fibrillation (OR, 14.0; 95% CI, 4.8–40.8), and active neoplasm (OR, 7.1; 95% CI, 1.4–36.2) were associated with cardioembolic stroke. Conclusions. Although a cohort of young and healthy men with cardioembolic and large vessel occlusions can be distinguished using both clinical sub-grouping and unsupervised clustering, stroke in other patients may be explained based on the existing comorbidities.

“…Data by Daniel Chan and colleagues [1] from “All New Zealand Acute Coronary Syndrome Quality Improvement Registry”, a nationwide web-based electronic database, recently published in The Lancet Regional Health – Western Pacific , examined all patients admitted to an New Zealand Hospital with Acute Coronary Syndromes (ACS) who underwent coronary angiography during the lockdown (23 March –26 April 2020) respect with equivalent weeks in 2015–2019. Ambulance attendances and regional community troponin-I testing were also compared for lockdown and non-lockdown (1 July 2019 to 16 February 2020) periods.…”

“…In the study by Daniel Chan and colleagues [1] , hospitalisations for ACS for 5 weeks during the lockdown were analysed; the results documented a clear reduction in hospitalisations (105 vs. 146 per-week, rate ratio 0 · 72 [95% CI 0 · 61–0 · 83], p = 0.003). In particular, the major component of this reduction involved myocardial infarctions without ST-segment elevation (NSTE-ACS; p = 0 · 002), while there were no significant differences in ST-segment elevation heart attacks (STEMI; p = 0 · 31) and door to balloon time (70 vs. 72 min, p = 0 · 52).…”

As the COVID-19 pandemic enters its third year and the omicron variant becomes dominant, we propose an alternative strategy for dealing with COVID-19, called hybrid lockdown, that is, the combination of lockdown (the centralized and organized lockdown of the high-risk population) and free mobility (normal mobility) of the low-risk population. Such an approach will enable a country or region, especially with a high population density, to achieve significant prevention and control the effects of the COVID-19 pandemic at the least cost.
