Cardio-Ankle Vascular Index Reflects Impaired Exercise Capacity and Predicts Adverse Prognosis in Patients With Heart Failure.

ABSTRACT: Aims: We aimed to assess the associations of CAVI with exercise capacity in heart failure (HF) patients. In addition, we further examined their prognosis. Methods: We collected the clinical data of 223 patients who had been hospitalized for decompensated HF and had undergone both CAVI and cardiopulmonary exercise testing. Results: For the prediction of an impaired peak oxygen uptake (VO₂) of < 14 mL/kg/min, receiver-operating characteristic curve demonstrated that the cutoff value of CAVI was 8.9. In the multivariate logistic regression analysis for predicting impaired peak VO₂, high CAVI was found to be an independent factor (odds ratio 2.343, P = 0.045). We divided these patients based on CAVI: the low-CAVI group (CAVI < 8.9, n = 145) and the high-CAVI group (CAVI ≥ 8.9, n = 78). Patient characteristics and post-discharge cardiac events were compared between the two groups. The high-CAVI group was older (69.0 vs. 58.0 years old, P < 0.001) and had lower body mass index (23.0 vs. 24.1 kg/m², P = 0.013). During the post-discharge follow-up period of median 1,623 days, 58 cardiac events occurred. The Kaplan-Meier analysis demonstrated that the cardiac event rate was higher in the high-CAVI group than in the low-CAVI group (log-rank P = 0.004). The multivariate Cox proportional hazard analysis revealed that high CAVI was an independent predictor of cardiac events (hazard ratio 1.845, P = 0.035). Conclusion: High CAVI is independently associated with impaired exercise capacity and a high cardiac event rate in HF patients.

Project description:Human immunodeficiency virus (HIV) infection is associated with increased cardiovascular diseases (CVDs) even in patients with viral suppression by combination antiretroviral therapy (cART). Arterial stiffness is an independent predictor of CVDs in diseased individuals and the general population. Cardio-ankle vascular index (CAVI) is an index of arterial stiffness that has been shown to predict target organ damage. CAVI is less studied in HIV patients. We compared the levels of arterial stiffness using CAVI and associated factors among cART-treated and cART-naïve HIV patients to those of non-HIV controls. In a case-control design, 158 cART-treated HIV patients, 150 cART-naïve HIV patients and 156 non-HIV controls were recruited from a periurban hospital. We collected data on CVD risk factors, anthropometric characteristics, CAVI, and fasting blood samples to measure plasma glucose, lipid profile, and CD4+ cell counts. Metabolic abnormalities were defined using the JIS criteria. CAVI increased in cART-treated HIV patients compared to cART-naïve HIV patients and non-HIV controls (7.8 ± 1.4 vs 6.6 ± 1.1 vs 6.7 ± 1.4 respectively, p < 0.001). CAVI was associated with metabolic syndrome in non-HIV controls [OR (95% CI) = 2.14 (1.04-4.4), p = 0.039] and cART-naïve HIV patients [1.47 (1.21-2.38), p = 0.015], but not in cART-treated HIV patients [0.81 (0.52-1.26), p = 0.353]. In cART-treated HIV patients, a tenofovir (TDF)-based regimen (β = -0.46, p = 0.023) was associated with decreased CAVI and decreased CD4+ cell count (β = -0.23, p = 0.047) was associated with increased CAVI. In a periurban hospital in Ghana, compared to non-HIV controls or cART-naïve HIV patients, cART-treated HIV patients had increased arterial stiffness measured as CAVI. CAVI is associated with metabolic abnormalities in non-HIV controls and cART-naïve HIV patients, but not in cART-treated HIV patients. Patients on TDF-based regimens had decreased CAVI.

Project description:BackgroundArterial stiffness causes cardiovascular disease and target-organ damage. Carotid-femoral pulse wave velocity is regarded as a standard arterial stiffness metric. However, the prognostic value of cardio-ankle vascular index (CAVI), which is mathematically corrected for blood pressure, remains understudied.ObjectivesThe purpose of this study was to determine the association of CAVI with cardiovascular and kidney outcomes.MethodsPubMed, Scopus, and Web of Science were searched until May 6, 2023, for longitudinal studies reporting the association of CAVI with mortality, cardiovascular events (CVEs) (including death, acute coronary syndromes, stroke, coronary revascularization, heart failure hospitalization), and kidney function decline (incidence/progression of chronic kidney disease, glomerular filtration rate decline). Random-effects meta-analysis was performed. Studies were assessed with the "Quality in Prognostic Studies" tool.ResultsSystematic review identified 32 studies (105,845 participants; follow-up range: 12-148 months). Variable cutoffs were reported for CAVI. The risk of CVEs was higher for high vs normal CAVI (HR: 1.46 [95% CI: 1.22-1.75]; P < 0.001; I2 = 41%), and per SD/unit CAVI increase (HR: 1.30 [95% CI: 1.20-1.41]; P < 0.001; I2 = 0%). Among studies including participants without baseline cardiovascular disease (primary prevention), higher CAVI was associated with first-time CVEs (high vs normal: HR: 1.60 [95% CI: 1.15-2.21]; P = 0.005; I2 = 65%; HR per SD/unit increase: 1.28 [95% CI: 1.12-1.47]; P < 0.001; I2 = 18%). There was no association between CAVI and mortality (HR = 1.31 [0.92-1.87]; P = 0.130; I2 = 53%). CAVI was associated with kidney function decline (high vs normal: HR = 1.30 [1.18-1.43]; P < 0.001; I2 = 38%; HR per SD/unit increase: 1.12 [95% CI: 1.07-1.18]; P < 0.001; I2 = 0%).ConclusionsHigher CAVI is associated with incident CVEs, and this association is present in the primary prevention setting. Elevated CAVI is associated with kidney function decline.
