Background There is still much controversy concerning the impact of gender on mortality during ST-segment elevation myocardial infarction (STEMI). The COVID-19 pandemic deeply affected the clinical history of these patients, both in terms of presentation time and management. The aim of our study was to evaluate the impact of female gender on acute and mid-term mortality in STEMI patients hospitalized during the pandemic period. Materials and Methods Our study focuses on STEMI patients hospitalized during the darkest period of the pandemic. We retrospectively analyzed consecutive STEMI patients hospitalized from 15 March 2020 to 15 March 2021 in our Hub centre in Milan, Lombardy. All clinical, demographic, and procedural characteristics were collected in a dedicated database. Patient follow-up was carried out through clinical visits, telephone calls and remote monitoring through the “Lombardia Regional Registry”. Results From a total of 283 patients, women represented 26.8% of the population, with a mean age of 72 - 11.2 years vs. 64.7 - 12.6 years in men. Anterior STEMI was the most represented with a mildly reduced ejection fraction (EF 48.3 _ 11.8%) similar between genders. Coronary angiography showed more extensive disease in man, while women presented with a higher Killip class at admission and a more pronounced anemic status. In-hospital and 1-year mortality of the whole cohort were 11.4% and 7.5%, respectively, with no significant differences between genders (14.5% women vs. 10.6% men, p = ns; 9.2% women vs. 7% man, p = ns). EF resulted in being the only independent predictor of mortality in the short-term and at 1-year follow up in both genders. In the acute phase, the only other independent predictor of mortality was COVID-19 infection, secondary to the higher rate of respiratory omplications, without any difference in terms of major adverse cardiac events. The impact of COVID-19 infection on mortality was completely lost at 1-year follow up. Conclusions Our study has shown that female gender in STEMI patients does not represent an independent predictor of mortality both in the short- and in the mid-term follow up. Concomitant COVID-19 infection significantly influenced in-hospital mortality due to the higher rate of respiratory complications in both genders. The impact of COVID-19 on mortality was completely lost at follow-up, where age and a reduced EF remained the only independent predictors, regardless of gender.

Spontaneous coronary artery dissection (SCAD) is a rare clinical condition, but frequently manifested as acute myocardial infarction. In this particular setting, in recent years, optical coherence tomography (OCT) has been established as a possible diagnostic method due to the high spatial resolution (10–20 μm), which can visualize the different layers of coronary vessels. OCT can better analyze the “binary” or double lumen morphology, typical of this entity. Furthermore, it can identify the entrance breach and the circumferential and longitudinal extension of the lesion. However, we have to emphasize that this technique is not free from complications. OCT could further aggravate a dissection or exacerbate a new intimal tear. Therefore, the use of OCT in the evaluation of SCAD should be defined by balancing the diagnostic benefits versus procedural risks. Moreover, we underline that as SCAD is a rare condition and OCT is a recently introduced technique in clinical practice, limited data is available in literature.

Aims Mild cognitive impairment (MCI) is characterized by objective evidence of cognitive impairment in one or more cognitive domains in the absence of significant interference in daily-life activities. Anyway, people with MCI are considered to be at heightened risk of further cognitive decline and progression to dementia. To date, few evidence regarding the association between cardiovascular data and MCI are present in the literature. To investigate the association between various cardiovascular data (traditional risk factors and outcomes) and the development and progression of MCI. Methods and results The study included 127 patients referred to the Neurological Unit of the Fondazione IRCCS Ca’ Granda Ospedale Maggiore Policlinico of Milan for subjective memory complaints and/or clinical suspect of cognitive impairment. Neuropsychological tests evaluating executive functions and cardiovascular data were collected at baseline and 2-year follow-up. Visit reports and medical records were reviewed to extrapolate the data. The study was conducted between 2012 and 2020. The 51 (40.2%) patients on antiplatelet therapy (94% on aspirin) had a worse baseline degree of cognitive impairment on neuropsychological tests of executive functions and had greater worsening of MCI at 2 years (Table 1). Patients on antiplatelet therapy were significantly older (75.85 vs. 71.7; P = 0.009), more ischaemic (21.6% vs. 1.3%; P Conclusions The present study suggests that the prevalence and progression of MCI is significantly higher among patients on antiplatelet therapy, who carry a greater cardiovascular burden. Although patients on antiplatelet therapy were older, more ischaemic, hypertensive, and dyslipidaemic than patients without antiplatelet therapy, none of these parameters were associated with MCI presence and/or progression and can therefore be considered a confounding factor.
