| Abstract | BACKGROUND: Chronic heart failure (CHF) is an established risk factor of atrial fibrillation (AF), but the prognostic value of cardiac and hemodynamic parameters in assessing the risk of developing AF among patients with CHF is less defined. METHODS AND RESULTS: We followed an outpatients cohort of CHF patients secondary to left ventricular (LV) systolic dysfunction, who were free of AF at baseline. All patients underwent clinical evaluation, comprehensive echocardiography, and blood drawing in the same morning. Aortic pulse wave velocity (aPWV), a measure of aortic stiffness, was determined by Doppler echocardiography. A total of 77 patients (age 63 ± 9 years; 79% male) with mean LVEF (34 ± 8%) formed the study population. Fifteen patients developed incidental AF. At baseline, CHF patients who developed AF during follow-up had higher E-wave velocity (75 ± 2 cm/sec vs. 60 ± 2 cm/sec; P = 0.02), higher difference duration between mitral and pulmonary vein A velocity (A'-A), (10 ± 35 msec vs. 43 ± 44 msec P = 0.02), aPWV (7.1 ± 2.6 vs. 5.3 ± 1.9 m/sec P = 0.004), and furosemide dosage (110 ± 145 mg vs. 49 ± 48 mg P = 0.01) than those remaining free from AF. The two groups of patients did not significantly differ in terms of NYHA, LV volumes, ejection fraction, left atrial volume, creatinine, hemoglobin, renin, epinephrine, amino-terminal propeptide of type III and I procollagens, ACE inhibitor, and ß-blocker dose (P > 0.1 for all). Notably, higher aPWV (P = 0.01) and longer A-A' duration (P = 0.04) were associated with an increased incidence of AF, independently of potential confounders. CONCLUSIONS: Increased aortic stiffness and LV diastolic dysfunction are strong predictors of new onset of AF among patients with systolic CHF. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
