"Missing" acute coronary syndrome hospitalizations during the COVID-19 era in Greece: Medical care avoidance combined with a true reduction in incidence?

BACKGROUND: Reports from countries severely hit by the COVID-19 pandemic suggest a decline in acute coronary syndrome (ACS)-related hospitalizations. The generalizability of this observation on ACS admissions and possible related causes in countries with low COVID-19 incidence are not known. HYPOTHESIS: ACS admissions were reduced in a country spared by COVID-19. METHODS: We conducted a nationwide study on the incidence rates of ACS-related admissions during a 6-week period of the COVID-19 outbreak and the corresponding control period in 2019 in Greece, a country with strict social measures, low COVID-19 incidence, and no excess in mortality. RESULTS: ACS admissions in the COVID-19 (n = 771) compared with the control (n = 1077) period were reduced overall (incidence rate ratio [IRR]: 0.72, P < .001) and for each ACS type (ST-segment elevation myocardial infarction [STEMI]: IRR: 0.76, P = .001; non-STEMI: IRR: 0.74, P < .001; and unstable angina [UA]: IRR: 0.63, P = .002). The decrease in STEMI admissions was stable throughout the COVID-19 period (temporal correlation; R2 = 0.11, P = .53), whereas there was a gradual decline in non-STEMI/UA admissions (R2 = 0.75, P = .026) following the progressively stricter social measures. During the COVID-19 period, patients admitted with ACS presented more frequently with left ventricular systolic impairment (22.2 vs 15.5% control period; P < .001). CONCLUSIONS: We observed a reduction in ACS hospitalizations during the COVID-19 outbreak in a country with strict social measures, low community transmission, and no excess in mortality. Medical care avoidance behavior is an important factor for these observations, while a true reduction of the ACS incidence due to self-isolation/quarantining may have also played a role.

Atrial Fibrillation and Shock: Unmasking Theophylline Toxicity.

OBJECTIVE: The aim of this report is to describe a case of atrial fibrillation and shock precipitated by deliberate self-poisoning with theophylline. CLINICAL PRESENTATION AND INTERVENTION: An 85-year-old male with severe theophylline intoxication in a suicide attempt was admitted with severe cardiac arrhythmia and shock; despite poor prognosis, he fully recovered gradually after proper diagnosis and treatment. Theophylline is a rather forgotten medication; thus, intoxication is not usually considered among the etiologies of potentially treatable cardiologic emergencies, especially when its use is intentionally concealed. CONCLUSION: This case highlights the importance of identifying a comprehensive medication history using all available sources of information as early as possible in an emergency department presentation.
