Chest Pain in Women: Considerations From the 2021 AHA/ACC Chest Pain Guideline.

Chest pain is a common concern of women evaluated in both the inpatient and outpatient setting. There are significant differences in pathophysiology when comparing coronary artery disease (CAD) in women and men, including a higher prevalence of nonobstructive CAD. Furthermore, significant sex disparities exist in the care of women with acute coronary syndromes that stem from factors such as delays in diagnosis and inconsistencies in treatment. The 2021 AHA/ACC/Multisociety Guideline for the Evaluation and Diagnosis of Chest pain is an important document comprised of recommendations for the assessment of acute and stable chest pain. In this review, we discuss key points from the guideline in the context of evaluating chest pain in women. We discuss the similarities and differences of chest pain presentation between the sexes, evaluation of chest pain in patients with known nonobstructive CAD and ischemia with no obstructive coronary arteries, and considerations for cardiac imaging during pregnancy.

Optimal waist circumference cutoff values to predict cardiometabolic alterations in a Venezuela national representative sample. The EVESCAM study / Valores óptimos de punto de corte de circunferencia abdominal para predecir alteraciones cardiometabólicas en una muestra representativa nacional de Venezuela. El estudio EVESCAM

Abstract Objective: Waist circumference (WC) value reflects abdominal adiposity, but the amount abdominal fat that is associated to cardiometabolic risk factors varies among ethnicities. Determination of metabolic abnormalities has not undergone a WC adaptation process in Venezuela. The aim of the study was (1) to determine the optimal WC cutoff value associated with ≥2 cardiometabolic alterations and (2) incorporating this new WC cutoff, to determine the prevalence of abdominal obesity and cardiometabolic risk factors related in Venezuela. Methods: The study was national population-based, cross-sectional, and randomized sample, from 2014 to 2017. To assess performance of WC for identifying cardiometabolic alterations, receiver operating characteristics curves, area under the curve (AUC), sensitivity, specificity, and positive likelihood ratios were calculated. Results: Three thousand three hundred eighty-seven adults were evaluated with mean age of 41.2 ± 15.8 years. Using the best tradeoff between sensitivity and specificity, WC cutoffs of 90 cm in men (sensitivity = 72.4% and specificity = 66.1%) and 86 cm in women (sensitivity = 76.2% and specificity = 61.4%) were optimal for aggregation of ≥2 cardiometabolic alterations. AUC was 0.75 in men and 0.73 in women using these new cutoffs. Prevalence of abdominal obesity and metabolic syndrome was 59.6% (95 CI; 57.5-61.7) and 47.6% (95 CI; 45.2-50.0), respectively. Cardiometabolic risk factors were associated with being men, higher age, adiposity, and living in northern or western regions. Conclusion: The optimal WC values associated with cardiometabolic alterations were 90 cm in men and 86 cm in women. More than half of the Venezuelan population had abdominal obesity incorporating this new WC cutoff.

Resumen Objetivo: El valor de la circunferencia abdominal (CA) refleja la adiposidad abdominal, pero la cantidad de grasa abdominal asociada a factores de riesgo cardiometabólicos varía según la etnia. La determinación de anomalías metabólicas no se ha adaptado a la CA en Venezuela. 1) Detrerminar el valor de corte óptimo de CA asociados a ≥ 2 alteraciones cardiometabólicas. 2) Incorporando este nuevo límite de CA, determinar la prevalencia de obesidad abdominal y factores de riesgo cardiometabólicos relacionados en Venezuela. Métodos: Fue un estudio poblacional, transversal, de muestreo aleatorio de 2014 a 2017. Para evaluar el valor de CA para identificar alteraciones cardiometabólicas, se realizaron curvas características operativa del receptor y se calculó área bajo la curva (ABC), sensibilidad, especificidad y razón de similitud. Resultados: se evaluaron 3387 adultos con una edad promedio de 41.2 ± 15.8 años. Utilizando la mejor relación entre sensibilidad y especificidad, se determinó que los valores de corte de 90 cm en hombres (sensibilidad = 72.4% y especificidad = 66.1%) y 86 cm en mujeres (sensibilidad = 76.2% y especificidad = 61.4%) fueron óptimos para la agregación de ≥ 2 alteraciones cardiometabólicas. El ABC fue de 0,75 en hombres y de 0,73 en mujeres usando estos nuevos puntos de corte. La prevalencia de obesidad abdominal y síndrome metabólico fue 59.6% (95IC; 57.5 - 61.7) y 47.6% (95CI; 45.2 - 50.0), respectivamente. La presencia de factores de riesgo cardiometabólicos se asoció con ser hombre, mayor edad, adiposidad y vivir en regiones del norte o del oeste. Conclusión: Los valores óptimos de CA asociados con alteraciones cardiometabólicas fueron 90 cm en hombres y 86 cm en mujeres. Más de la mitad de la población venezolana tenía obesidad abdominal al incorporar este nuevo corte de CA.
