Kounis Syndrome: A Sting to the Heart.

A 67-year-old woman experienced pruritus, an urticarial rash, and acute, pressure-like chest pain following an insect sting. Initial electrocardiographic findings were notable for ST-segment elevations in the inferior leads without reciprocal changes, but a follow-up electrocardiogram showed pronounced ST-segment elevations in the inferior leads with reciprocal changes. Her troponin I level peaked at 3,053 pg/mL, and she was transferred to a large academic center for percutaneous coronary intervention. Balloon angioplasty was performed for 95% thrombotic occlusion of the mid-right coronary artery, and a drug-eluting stent was placed. The patient's presentation was consistent with type II Kounis syndrome.

Associations of empirical dietary inflammatory index with heart failure in adults from the United States.

BACKGROUND: Recent evidence has shown associations between cardiovascular disease and a proinflammatory diet. We hypothesized that a proinflammatory diet, assessed using the Empirical Dietary Inflammatory Index (EDII), is associated with increased risk of prevalent heart failure (HF). METHODS: This analysis included 13,687 participants (44.8 ± 19.4 years; 45.7% male, 67.8% whites) from the Third National Health and Nutrition Examination Survey. EDII score was calculated from the Food Frequency Questionnaire. Prevalent HF was determined by physician-diagnosed self-report. Multivariable logistic regression analysis was used to calculate odds ratios (OR) and 95% confidence intervals (CI) for the association between EDII score and prevalent HF across tertiles (reference group first tertile) and per 1-unit standard deviation (1-SD) increase. RESULTS: About 1.4% (n = 190) of the participants reported a history of HF. Each 1-SD increase in EDII score (0.276) conferred 25% increased odds of prevalent HF (OR (95% CI): 1.25 (1.07-1.46); p value = 0.006). Odds of HF increased as EDII tertile increased, indicating a dose-response relationship (OR (95% CI) for 2nd and 3rd tertiles compared to 1st tertile: 1.42 (0.99-2.04), 1.68 (1.15-2.46), respectively). These results were consistent in subgroups of the participants stratified by demographics and comorbidities. CONCLUSIONS: Proinflammatory dietary patterns are associated with an increased risk of HF. The risk of HF could potentially be reduced by avoiding proinflammatory dietary patterns.

Hypertension Across a Woman's Life Cycle.

PURPOSE OF REVIEW: We reviewed the effects of hypertension and the means to prevent and treat it across the spectrum of a woman's lifespan and identified gaps in sex-specific mechanisms contributing to hypertension in women that need to be addressed. RECENT FINDINGS: Hypertension continues to be an important public health problem for women across all life stages from adolescence through pregnancy, menopause, and older age. There remain racial, ethnic, and socioeconomic differences in hypertension rates not only overall but also between the sexes. Blood pressure cutoffs during pregnancy have not been updated to reflect the 2017 ACC/AHA changes due to a lack of data. Additionally, the mechanisms behind hypertension development in menopause, including sex hormones and genetic factors, are not well understood. In the setting of increasing inactivity and obesity, along with an aging population, hypertension rates are increasing in women. Screening and management of hypertension throughout a women's lifespan are necessary to reduce the burden of cardiovascular disease, and further research to understand sex-specific hypertension mechanisms is needed.

A Case Report of Immune Checkpoint Inhibitor-Induced Aortitis Treated with Tocilizumab.

Vasculitic immune checkpoint inhibitor-related adverse events (irAEs) are rare, with limited data to guide their management. Here, we present a case of a 67-year-old female with stage IV cutaneous melanoma who received first-line pembrolizumab. She had completed 21 cycles of pembrolizumab dosed at 200 mg every 21 days over 15 months when she developed fatigue, chills, decreased appetite, night sweats, nausea, diarrhea, dry cough, and chest pain. A routine, staging positron emission tomography (PET) scan revealed aortitis of the transverse aortic arch. An extensive workup was unremarkable for other causes, so her condition was labeled a grade III immune-related vasculitis. Based on this diagnosis, we started high-dose prednisone and discontinued pembrolizumab. After two months of high-dose prednisone, she developed bothersome weight gain and insomnia, leading to a switch from prednisone to tocilizumab as a steroid-sparing agent. The selection of tocilizumab was based on its routine use for giant cell arteritis which can have extracranial symptoms including thoracic aortitis. Her symptoms resolved, and subsequent PET scans showed resolution of the aortitis and no evidence of metastatic melanoma. As the indications for immunotherapy expand, rare complications are becoming more prevalent, and more data will be needed to guide their management. While there is evidence for tocilizumab use as a steroid-sparing treatment for large-vessel vasculitides due to other conditions, this is the first case of its use to treat an aortitis irAE to our knowledge. In this case, it was an effective means of treating the patient while sparing them from prolonged corticosteroids.

Avoidance of ST-Segment-Elevation Myocardial Infarction Treatment for >1 Week Due to COVID-19 Fears.

During the coronavirus disease 2019 (COVID-19) pandemic, social distancing guidelines have negatively affected the care-seeking behavior of patients with chronic medical conditions, including those with cardiovascular disease. We report the case of a 60-year-old man with vague gastrointestinal symptoms who waited more than 1 week to seek treatment for fear of COVID-19 infection. On presentation at another hospital, he was found to have had an anterior myocardial infarction, and he underwent percutaneous coronary intervention to stent an occluded proximal left anterior descending coronary artery. Subsequently, the patient experienced refractory cardiogenic shock and, during his transfer to our hospital, refractory ventricular tachycardia, which ultimately proved fatal.
