RESUMEN
BACKGROUND: Previous studies have suggested that frequent toothbrushing is associated with a lower risk of future cardiovascular events. We sought to investigate further the relationship between toothbrushing, cardiovascular risk factors, and lifestyle behaviours. METHODS: We analysed a cross-sectional survey including 13,761 adults aged 30 years or older without a history of cardiovascular diseases from the Korean National Health and Nutritional Examination Survey. Conventional cardiovascular risk factors (blood pressure, lipid profiles, and fasting glucose), and inflammatory markers (high-sensitivity C-reactive protein [hsCRP], and white blood cell counts [WBC]) were investigated in relation to the frequency of toothbrushing. RESULTS: The estimated 10-year atherosclerotic cardiovascular disease (ASCVD) risk, calculated using the pooled cohort equations was 13.7%, 9.1%, and 7.3% for participants who reported toothbrushing 0-1, 2, and ≥ 3 times a day, respectively. Both conventional risk factors and inflammatory markers were significantly associated with frequent toothbrushing. However, after adjusting potential confounding factors such as age, sex, comorbidities, and lifestyle behaviours, only inflammatory markers were remained as significant factors. CONCLUSIONS: Oral hygiene behaviours are closely linked to cardiovascular risk factors. This study suggests that reduced systemic inflammatory burden may explain the benefit of improved oral hygiene in terms of cardiovascular risk.

BACKGROUND: The left ventricular global longitudinal strain (LVGLS) and left atrial reservoir strain (LARS) are considered as sensitive and reliable markers of cardiac remodeling and function. However, their temporal changes during optimal management of heart failure with reduced ejection fraction (HFrEF) are unknown. OBJECTIVES: This study investigated the time trajectories of the LARS and LVGLS in patients with HFrEF treated with angiotensin receptor-neprilysin inhibitors, and assessed whether the LARS and LVGLS could define left heart reverse remodeling (LHRR) and reflect the treatment response and prognosis. METHODS: Using a retrospective cohort of patients with HFrEF prescribed sacubitril/valsartan, we assessed the time trajectories of the LVGLS and LARS in 409 patients (1,258 echocardiograms), and investigated their association with the occurrence of cardiovascular death and hospitalization for heart failure (HHF), after the determination of LHRR, during a median follow-up of 27.1 (IQR: 18.3-36.3) months. RESULTS: Among patients with HFrEF prescribed sacubitril/valsartan, both the LVGLS and LARS improved over time. The improvements in the LVGLS and LARS were prominent within 6 months of sacubitril/valsartan treatment: the LVGLS improved from 10.2% (IQR: 7.9%-12.7%) to 13.9% (IQR: 10.5%-16.3%) (P < 0.001), and the LARS improved from 11.4% (IQR: 8.4%-15.6%) to 15.9% (IQR: 11.5%-21.4%) (P < 0.001). These improvements were larger among patients who did not experience the study outcome than in patients with events. Improvement in the LVGLS to ≥13% and LARS to ≥12.5% (ie, complete LHRR) was significantly associated with a lower risk of cardiovascular death and HHF, and this association was stronger than that of changes in other conventional echocardiographic parameters. CONCLUSIONS: In patients with HFrEF treated with sacubitril/valsartan, the LVGLS and LARS were improved, typically within 6 months of treatment. Complete LHRR, defined by improvement in the LVGLS and LARS, can be an indicator of treatment response and prognosis.

AIMS: Despite well-established benefits of sacubitril/valsartan for cardiac reverse remodelling and the prognosis of patients with heart failure with reduced ejection fraction (HFrEF), there are some patients with limited therapeutic response, even with optimal therapy. We assessed the treatment response to sacubitril/valsartan in patients with HFrEF, focusing on the association between reverse remodelling and the prognosis. METHODS AND RESULTS: Using a retrospective cohort of consecutive patients with HFrEF treated with sacubitril/valsartan, we compared the time trajectory of cardiac function in 415 patients (1258 echocardiograms), according to the occurrence of cardiovascular death and hospitalization for HF during a median follow-up of 19.1 (interquartile range, 10.9-27.6) months. A higher sacubitril/valsartan dose was associated with a better prognosis, whereas advanced age, diabetes, left ventricular (LV) hypertrophy, left atrial enlargement, and pulmonary hypertension were associated with a worse prognosis. Patients without an event (n = 337; 81.2%) showed LV reverse remodelling (LV ejection fraction ≥45% or LV end-systolic volume reduction by 15% from baseline), which was typically observed within 6 months of sacubitril/valsartan treatment. Reverse remodelling achievement was significantly associated with a better prognosis. However, patients without reverse remodelling had a worse prognosis, as poor as that in patients with HFrEF not treated with sacubitril/valsartan. CONCLUSIONS: In patients with HFrEF treated with sacubitril/valsartan, LV reverse remodelling reflects the treatment response and predicts the prognosis, whereas a lack of reverse remodelling indicates the lack of treatment benefits. Prediction and assessment of reverse remodelling may facilitate the selection of patients with greater benefits by sacubitril/valsartan.

BACKGROUND: Although electrocardiography and cardiac troponin play important roles in the diagnosis of acute coronary syndrome (ACS), there remain unmet clinical needs. Heart-type fatty acid-binding protein (H-FABP) has been identified as an early diagnostic marker of acute myocardial infarction (AMI). In this study, we examined the diagnostic and prognostic value of H-FABP in patients suspected with ACS. METHODS: We conducted an observational single-center cohort study, including 89 adults aged 30 years or older, who presented to the emergency room (ER) within 24 hours after the onset of chest pain and/or dyspnea. We performed laboratory analysis and point-of-care testing (POCT) for cardiac markers, including H-FABP, troponin I, and creatine kinase-myocardial band. We also evaluated the correlation between cardiac markers and left ventricular (LV) dysfunction and extent of coronary artery disease (CAD). RESULTS: In patients presented to ER within 4 hours after symptom onset (n = 49), the diagnostic accuracy of H-FABP for AMI, as quantified by the area under the receiver operating characteristic curve, was higher (0.738; 95% confidence interval [CI], 0.591-0.885) than other cardiac markers. In POCT, the diagnostic accuracy of H-FABP (56%; 95% CI, 45-67) was significantly higher than other cardiac markers. H-FABP was correlated with not extent of CAD but post-AMI LV dysfunction. CONCLUSION: H-FABP is a useful cardiac marker for the early diagnosis of AMI and prediction of myocardia injury. Difference in the circulatory release timeline of cardiac markers could explain its utility in early-stage of myocardial injury.
