We present the case of a woman who developed presumed spontaneous coronary artery dissection of a septal branch. She later developed high-grade atrioventricular block that led to a diagnosis of cardiac sarcoidosis involving the interventricular septum. This case illustrates a rare and challenging presentation of cardiac sarcoidosis. (Level of Difficulty: Beginner.), Central Illustration

ST elevations (STE) in the perioperative setting can result from a number of different etiologies, the most common and feared being acute coronary syndrome (ACS). However, other causes should be considered, as treatment may differ depending on the diagnosis. Here, we describe a case of STE and ventricular tachycardia in a patient at high risk for ACS. The patient had a prior diagnosis of coronary vasospasm; however, given pre-existing risk factors, much consideration and deliberation occurred prior to electing conservative therapy. This report provides an overview of perioperative vasospasm and other causes of STE, which anesthesiologists should be aware of.

Objectives: To characterize the impact of obesity on disease severity in patients with coronavirus disease 2019. Design: This was a retrospective cohort study designed to evaluate the association between body mass index and risk of severe disease in patients with coronavirus disease 2019. Data were abstracted from the electronic health record. The primary endpoint was a composite of intubation or death. Setting: Two hospitals in Massachusetts (one quaternary referral center and one affiliated community hospital). Patients: Consecutive patients hospitalized with confirmed coronavirus disease 2019 admitted between March 13, 2020, and April 3, 2020. Interventions: None. Measurements and Main Results: A total of 305 patients were included in this study. We stratified patients by body mass index category: < 25 kg/m2 (54 patients, 18%), ≥ 25 kg/m2 to < 30 kg/m2 (124 patients, 41%), ≥ 30 kg/m2 to < 35 kg/m2 (58 patients, 19%), and ≥ 35 kg/m2 (69 patients, 23%). In total, 128 patients (42%) had a primary endpoint (119 patients [39%] were intubated and nine died [3%] without intubation). Sixty-five patients (51%) with body mass index greater than or equal to 30 kg/m2 were intubated or died. Adjusted Cox models demonstrated that body mass index greater than or equal to 30 kg/m2 was associated with a 2.3-fold increased risk of intubation or death (95% CI, 1.2–4.3) compared with individuals with body mass index less than 25 kg/m2. Diabetes was also independently associated with risk of intubation or death (hazard ratio, 1.8; 95% CI, 1.2–2.7). Fifty-six out of 127 patients (44%) with body mass index greater than or equal to 30 kg/m2 had diabetes, and the combination of both diabetes and body mass index greater than or equal to 30 kg/m2 was associated with a 4.5-fold increased risk of intubation or death (95% CI, 2.0–10.2) compared with patients without diabetes and body mass index less than 25 kg/m2. Conclusions: Among consecutive patients hospitalized with coronavirus disease 2019, obesity was an independent risk factor for intubation or death.

Background Experimental studies support a link between obesity and pulmonary hypertension (PH), yet clinical studies have been limited. This study sought to determine the association of obesity and pulmonary hemodynamic measures and mortality in PH. Methods and Results We examined patients undergoing right‐sided heart catherization (2005–2016) in a hospital‐based cohort. Multivariable regression models tested associations of body mass index and pulmonary vascular hemodynamics, with PH defined as mean pulmonary artery pressure >20 mm Hg, and further subclassified into precapillary, postcapillary, and mixed PH. Multivariable Cox models were used to examine the effect of PH and obesity on mortality. Among 8940 patients (mean age, 62 years; 40% women), 52% of nonobese and 69% of obese individuals had evidence of PH. Higher body mass index was independently associated with greater odds of overall PH (odds ratio, 1.34; 95% CI, 1.29–1.40; P P P P P P for interaction=0.02). Conclusions Obesity is independently associated with PH. PH is associated with greater mortality; this is modified by obesity such that obese patients with precapillary PH have lower mortality compared with nonobese counterparts. Further studies are needed to elucidate mechanisms underlying obesity‐related PH.
