Illness Perceptions in Patients with Premature Coronary Artery Disease: A Sex-Based Analysis 8 Years After the Diagnosis.

To assess illness perceptions in patients with premature atherosclerotic coronary artery disease (CAD), 717 adults with premature CAD (diagnosis of CAD in men age < 45 years and women age < 55 years) completed sociodemographic indices, the Beck's Depression Inventory-II, Beck Anxiety Inventory and the Brief Illness Perceptions 8 years after the diagnosis. Mean age was 49.59 ± 3.57 years for men and 57.72 ± 4.90 years for women at the time of study. Both sexes were treated through coronary artery bypass graft surgery, percutaneous coronary intervention, or medical treatment. Depressive and anxiety symptoms were significantly more prevalent among women. Generally, the patients believed that their disease was chronic and well controlled and that it had no considerable negative impact on their routine life. Overall, patients had a low concern about their illness. Women had a more negative perception of their disease than did men which may indicate their need for higher psychological support.

Percutaneous transvenous mitral commissurotomy: significance of echocardiographic assessment in prediction of immediate result.

BACKGROUND: The current study aims to identify demographic, clinical characteristics, echocardiographic and/or mitral valve morphological parameters that may predict the successful result of percutaneous transvenous mitral commissurotomy (PTMC).  METHODS: The medical records of 196 patients (48 males, mean age: 42.7 ± 11.5 years) who underwent PTMC were reviewed. Prior to PTMC, a combination of transthoracic and transesophageal echocardiography were used to investigate substantial mitral valve morphological subcomponents (thickening, mobility, calcification, and subvalvular thickness) and suitability for PTMC. The second transthoracic echocardiographic assessment was performed within six weeks after PTMC. Patients were divided into two categories of successful or unsuccessful according to PTMC results. Successful PTMC was defined as: final mitral valve area (MVA) ≥1.5 cm2 without a post-procedure mitral regurgitation (MR) grade >2. The significant predictor of the result was identified by comparing demographic data, initial echocardiographic assessments and mitral valve morphological scores within both groups.  RESULTS: The mean MVA increased from 1.0 ± 0.2 cm2 to 1.7 ± 0.4 cm2, and mitral valve mean gradient (MVMG) decreased from 11.5 ± 5.2 to 5.2 ± 3.3 mmHg (P < 0.001 for both). Successful results were obtained in 139 (70.9%) patients compared to unsuccessful results in 57 (29.1%). Unsuccessful results were due to suboptimal secondary MVA < 1.5 cm2 in 50 (25.5%) patients and post-procedure MR grade >2 in 7 (3.6%). Multiple logistic regression analysis indicated that young age, lower size of the left atrium (LA), and smaller degree of mitral valve thickness were the predictors of successful result.  CONCLUSION: Pre-procedure echocardiographic assessment appears to be helpful in predicting PTMC results. Successful PTMC is influenced by the patients' age, LA size, and mitral valve thickness.

Assessment of Left Ventricular Dyssynchrony in Heart Failure Patients Regarding Underlying Etiology and QRS Duration.

BACKGROUND: Left ventricular (LV) dyssynchrony is a prevalent feature in heart failure (HF) patients. The current study aimed to evaluate the prevalence of inter and intraventricular dyssynchrony in HF patients with regard to the QRS duration and etiology. METHODS: The available data on the tissue Doppler imaging (TDI) of 230 patients with refractory HF were analyzed. The patients were divided into three groups according to the QRS duration: QRS duration < 120 ms; 120-150 ms; and ≥ 150 ms and the patients were re-categorized into two subgroups depending on the underlying etiology: ischemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM). The time-to-peak myocardial sustained systolic velocity (Ts) in six basal and six middle segments of the LV was measured manually using the velocity curves from TDI. LV dyssynchrony was defined as interventricular mechanical delay ≥ 40 ms and tissue Doppler velocity all segments delay ≥ 105 ms; standard deviation (SD) of all segments ≥ 34.4 ms; basal segments delay ≥ 78 ms; SD of basal segments ≥ 34.5 ms; and opposing wall delay ≥ 65 ms. RESULTS: After adjustment for the possible confounders, interventricular dyssynchrony was more prevalent in the patients with QRS duration ≥ 150 ms than in those with QRS duration 120-150 ms and < 120 ms. The patients with DCM also had a higher percentage of interventricular dyssynchrony than those with ICM in the wide QRS groups. Turning to the intraventricular dyssynchrony indices, the patients with QRS duration ≥ 150 ms and 120-150 ms revealed a significantly greater delay between Ts at the basal and all segments than did those with QRS duration < 120 ms, while etiology did not influence the frequency of these indices in each QRS group. CONCLUSION: The prevalence of both inter and intraventricular dyssynchrony indices was greater in the patients with wide QRS than in those with narrow QRS duration. The underlying etiology may affect the frequency of interventricular but not intraventricular dyssynchrony indices.
