Sex-Related Differences in Patient Characteristics, Hemodynamics, and Outcomes of Cardiogenic Shock: INOVA-SHOCK Registry.

Background: Little is known about sex-related differences in outcomes of patients with cardiogenic shock (CS) treated within a standardized team-based approach (STBA). Methods: We evaluated 520 consecutive patients (151 women and 369 men) with CS due to acute myocardial infarction (AMI) and heart failure (HF) in a single-center registry (January 2017-December 2019) and examined outcomes according to sex and CS phenotype. The primary outcome was in-hospital mortality. Secondary outcomes included major adverse cardiac events, 30-day mortality, major bleeding, vascular complications, and stroke. Results: Women with AMI-CS had higher baseline acuity (CardShock score: female [F]: 5.5 vs male [M]: 4.0; P = .04). Women with HF-CS more often presented with cardiac arrest (F: 12.4% vs M: 2.4%; P< .01) and had higher rates of vasopressor use (F: 70.8% vs M: 58.0%; P = .04) and mechanical circulatory support (F: 46.1% vs M: 32.5%; P = .04). There were no sex-related differences in in-hospital mortality for AMI-CS (F: 45.2% vs M: 36.9%; P = .28) and HF-CS (F: 28.1% vs M: 24.5%; P = .56). Women with HF-CS experienced higher rates of major bleeding (F: 25.8% vs M: 13.7%; P = .02) and vascular complications (F: 15.7% vs M: 6.1%; P = .01). However, female sex was not an independent predictor of these complications. No sex differences in survival were noted at 1 year. Conclusions: Within an STBA, although women with AMI-CS and HF-CS presented with higher acuity, they experienced similar in-hospital mortality, major adverse cardiac events, 30-day mortality, stroke, and 30-day readmissions as men. Further research is needed to better understand the extent to which historical differences in CS outcomes can be mitigated by an STBA.

Spontaneous pneumomediastinum in COVID-19 pneumonia.

Spontaneous pneumomediastinum is a benign entity but can worsen the underlying condition with which it is associated. We evaluated the incidence and the clinical relevance of spontaneous pneumomediastinum in a consecutive series of 102 patients with COVID-19 pneumonia. Six cases of pneumomediastinum were identified by high-resolution chest CT-scan. Three patients required early intubation, and one of them died, while in in the remaining subjects the clinical course was benign. The presence of pneumomediastinum required some changes in the management of mechanical ventilation. In conclusion, spontaneous pneumomediastinum is a possible complication of severe COVID-19 pneumonia that can affect patient management and clinical outcomes.

Evaluation of systo-diastolic cardiac function and arterial stiffness in subjects with new diagnosis of coeliac disease without cardiovascular risk factors.

In literature, there are conflicting opinions on the development of cardiovascular disease risk in patients with coeliac disease (CD). The aim of the research was to identify in young subjects without cardiovascular risk factor and newly diagnosed CD, alterations in different instrumental parameters that are associated with an augmented cardiovascular risk. Twenty-one consecutive young adults with a new diagnosis of CD and without cardiovascular risk factors were prospectively enrolled and underwent transthoracic echocardiography to analyse ascending aorta elastic properties [including tissue Doppler imaging strain (TDI-ε)] and left ventricular 2D strains (global longitudinal, radial and circumferential), and applanation tonometry by SphygmoCor. Cases were compared with 21 age- and sex-matched healthy controls. Mean age of the cases was 38 ± 9 years and 15 of them (71%) were female. Brachial and central blood pressure was higher in the CD group. Elastic properties of the ascending aorta were all impaired in the CD group: TDI-ε was altered in 57% of cases (0% of controls, p < 0.001). Concentric remodelling and grade I diastolic dysfunction were present in 38% and 24% of cases, respectively (0% of controls, p < 0.001). Global longitudinal strain was normal in all subjects, while radial and circumferential strain were altered in 67% and 35%, respectively (0% of controls, p < 0.001). In young subjects without cardiovascular risk factor, a newly diagnosed CD is associated with altered aortic elastic properties, left ventricular concentric remodelling and diastolic dysfunction and altered radial and circumferential strain.
