Subclinical vascular composites predict clinical cardiovascular disease, stroke, and dementia: The Multi-Ethnic Study of Atherosclerosis (MESA).

BACKGROUND AND AIMS: Subclinical cardiovascular disease (CVD) measures may reflect biological pathways that contribute to increased risk for coronary heart disease (CHD) events, stroke, and dementia beyond conventional risk scores. METHODS: The Multi-Ethnic Study of Atherosclerosis (MESA) followed 6814 participants (45-84 years of age) from baseline in 2000-2002 to 2018 over 6 clinical examinations and annual follow-up interviews. MESA baseline subclinical CVD procedures included: seated and supineblood pressure, coronary calcium scan, radial artery tonometry, and carotid ultrasound. Baseline subclinical CVD measures were transformed into z-scores before factor analysis to derive composite factor scores. Time to clinical event for all-cause CVD, CHD, stroke and ICD code-based dementia events were modeled using Cox proportional hazards models reported as area under the curve (AUC) with 95% Confidence Intervals (95%CI) at 10 and 15 years of follow-up. All models included all factor scores together, and adjustment for conventional risk scores for global CVD, stroke, and dementia. RESULTS: After factor selection, 24 subclinical measures aggregated into four distinct factors representing: blood pressure, atherosclerosis, arteriosclerosis, and cardiac factors. Each factor significantly predicted time to CVD events and dementia at 10 and 15 years independent of each other and conventional risk scores. Subclinical vascular composites of atherosclerosis and arteriosclerosis best predicted time to clinical events of CVD, CHD, stroke, and dementia. These results were consistent across sex and racial and ethnic groups. CONCLUSIONS: Subclinical vascular composites of atherosclerosis and arteriosclerosis may be useful biomarkers to inform the vascular pathways contributing to events of CVD, CHD, stroke, and dementia.

Progression of subclinical cardiovascular disease in patients with HIV.

OBJECTIVE: Human immunodeficiency virus (HIV) infected patients are at increased risk of cardiovascular disease (CVD). Multidetector computed tomography (MDCT) stratifies cardiovascular risk in asymptomatic patients with subclinical atherosclerosis. The aim of this study was to determine the ability of MCTD and clinical and laboratory parameters to assess subclinical CVD progression in HIV patients. METHODS: Prospective longitudinal cohort study of patients with at least 10 years of HIV infection and 5 years of antiretroviral therapy history, low cardiovascular risk and monitored for 6 years (2015-2021). All patients underwent clinical assessment, blood analysis, carotid ultrasound, and gated MDCT in 2015 and 2021. RESULTS: Sixty-three patients (63.5% male) with a mean age of 49.9 years (standard deviation [SD], 10.5) were included in 2015; 63 of them were followed until 2021. Comparing the results from 2015 with those from 2021, Systematic Coronary Risk Estimation-2 (SCORE2) was 2.9% (SD, 2.1) vs. 4.4% (SD,3.1); Multi-Ethnic Study of Atherosclerosis score (MESA risk) was 3.4 (SD 5.8) vs. 6.0 (SD 8.6); coronary artery calcification CAC) score >100 was 11.1% vs. 25.4% (P < 0.05); and 11% vs. 27% had carotid plaques (P = 0.03). CONCLUSIONS: After six years of follow-up, an increase in SCORE2, carotid plaques, CAC scoring and MESA risk was observed. MDCT findings, along with other clinical and laboratory parameters, could play an important role as a marker of CVD progression in the evaluation of patients with HIV and low cardiovascular risk.

Enfermedad cardiovascular subclínica en familiares de mujeres con síndrome de ovario poliquístico y su asociación con la resistencia a la insulina / Subclinical Cardiovascular Disease in Relatives of Women with Polycystic Ovary Syndrome and its Association with Insulin Resistance

Introducción: Se ha demostrado que los familiares de mujeres con síndrome de ovario poliquístico tienen mayor frecuencia de factores de riesgo cardiovascular, tales como la resistencia a la insulina, la diabetes mellitus tipo 2, la dislipidemia y la hipertensión arterial. Por ende, estas personas presentan un mayor riesgo de desarrollar enfermedad cardiovascular. Objetivo: Determinar la frecuencia de enfermedad cardiovascular subclínica en familiares de primer grado de mujeres con y sin síndrome de ovario poliquístico y su relación con la resistencia a la insulina. Métodos: Se realizó un estudio descriptivo transversal en 36 familiares de primer grado de mujeres con el síndrome de ovario poliquístico e igual cantidad en familiares de mujeres sin la enfermedad. Ninguno de los miembros de ambos grupos tenía antecedentes de diabetes mellitus, prediabetes, dislipidemia e hipertensión arterial, ni obesidad. Para llevar a cabo la comparación de los resultados de las pruebas realizadas fueron pareados a razón de 1:1, por edad ± 5 años, parentesco, sexo e índice de masa corporal. Resultados: Con enfermedad cardiovascular subclínica hubo 21 familiares, 15 del grupo de estudio (71,4 por ciento) y del grupo control el 28,6 por ciento, (p < 0,05). De la totalidad de familiares del grupo de estudio, con resistencia a la insulina el 65,0 por ciento presentó enfermedad cardiovascular subclínica. En el grupo control, ninguno de los pacientes con insulinemia en ayunas normal tuvo enfermedad cardiovascular subclínica. Conclusiones: La enfermedad cardiovascular subclínica es más frecuente en los familiares de mujeres con síndrome de ovario poliquístico y la resistencia a la insulina se asocia de forma significativa a este padecimiento en ambos grupos(AU)

Introduction: Relatives of women with polycystic ovary syndrome have been show to present a higher frequency of cardiovascular risk factors, such as insulin resistance, type 2 diabetes mellitus, dyslipidemia and arterial hypertension. Therefore, these people have a higher risk for developing cardiovascular disease. Objective: To determine the frequency of subclinical cardiovascular disease in first-degree relatives of women with and without polycystic ovary syndrome and its relationship with insulin resistance. Methods: A cross-sectional and descriptive study was carried out with 36 first-degree relatives of women with polycystic ovary syndrome and with the same number of relatives of women without the disease. None of the members of both groups had a history of diabetes mellitus, prediabetes, dyslipidemia, high blood pressure, or obesity. To carry out the comparison of the results of the tests carried out, they were matched at a 1: 1 ratio, by age ± 5 years, relationship, sex and body mass index. Results: There were 21 relatives with subclinical cardiovascular disease, 71.4 percent of which belonged to the study group, why 28.6 percent belonged to the control group (P < 0.05). Of the total family members of the study group, with insulin resistance, 65.0 percent had subclinical cardiovascular disease. In the control group, with normal fasting insulinemia, none has subclinical cardiovascular disease. Conclusions: Subclinical cardiovascular disease is more frequent in the relatives of women with polycystic ovary syndrome, while insulin resistance is significantly associated with this condition in both groups(AU)
