Prolonged pulmonary pulse transit time is associated with symptoms in patients with significant mitral stenosis and sinus rhythm.

INTRODUCTION: Pulmonary pulse transit time (pPTT) is a novel noninvasive echocardiographic measure to assess pulmonary arterial hemodynamics. It has been shown to be shorter in precapillary pulmonary hypertension (PHT). Mitral stenosis (MS) is one of the causes of postcapillary PHT. We aimed to investigate pPTT in patients with MS and its relationship with symptoms. METHODS: We included 51 patients with MS (25 were asymptomatic, NYHA I, and 26 were symptomatic, NHYA II or III), and 50 controls, and evaluated their demographic characteristics and echocardiographic variables, including pPTT. RESULTS: Baseline characteristics, including age, sex, body mass index, and cardiovascular risk factors, were similar between the MS and the control group. The pPTT was longer in the MS group than in the control group (0.21 ± 0.08 vs 0.15 ± 0.05, P < .001). Patients with symptomatic MS had longer pPTT than asymptomatic patients (P = .005). The pPTT was positively correlated with left atrial volume index and systolic pulmonary artery pressure, and negatively with tricuspid annular plane systolic excursion (r = .432; P < .001, r = .319; P = .001, r = -.293; and P = .003, respectively). CONCLUSION: The measurement of pPTT appears clinically relevant in patients with PHT. Further studies evaluating whether it is useful in distinguishing precapillary from postcapillary PHT are required.

Association between depression and anxiety scores and inflammation in patients with isolated coronary artery ectasia.

OBJECTIVE: Depression and anxiety disorders are frequently found in combination with obstructive coronary artery disease. Coronary artery ectasia (CAE) is an atypical form of coronary artery disease, the etiology of which has not yet been clearly defined. The aim of this study was to assess the existence of a relationship between anxiety/depression and CAE. METHODS: A CAE group (n=41; mean age: 58.9±9.0 years) and a control group (n=42; mean age: 58.0±9.6 years) were compared. The anxiety and depression status of patients was evaluated using the Hospital Anxiety and Depression Scale (HADS) questionnaire. RESULTS: Age, sex, ejection fraction, and cardiovascular risk factor data were similar in both groups. The serum Creactive protein (CRP) and uric acid levels as well as the leukocyte count were significantly higher in the CAE group (p<0.05). The HADS anxiety score was higher in the CAE group, but without statistical significance (p=0.23). The HADS depression score and total HADS score was significantly higher in the CAE group (p<0.001 and p<0.001). The total HADS score and the HADS depression score were correlated with the serum CRP level (r=0.489; p<0.001 and r=0.543; p<0.001, respectively), whereas the anxiety score was not correlated with CRP (r=0.85; p=0.23). CONCLUSION: The depression score, CRP, and uric acid levels were greater in patients with isolated CAE compared with those of patients with normal coronaries. The anxiety score did not demonstrate a relationship to CAE; however, there was an association between the depression score and CRP, which is an inflammatory marker.
