Interrelations between albuminuria, electrocardiographic left atrial abnormality, and incident atrial fibrillation in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort.

Background: The objective of the study was to examine the joint associations of albuminuria and electrocardiographic left atrial abnormality (ECG-LAA) with incident atrial fibrillation (AF) and whether this relationship varies by race.

Methods: This analysis included 6670 participants free of clinical cardiovascular disease (CVD), including atrial fibrillation (AF), from the Multi-Ethnic Study of Atherosclerosis. ECG-LAA was defined as P-wave terminal force in V1 [PTFV1] >5000 μV × ms.

Volitional pursed lips breathing in patients with stable chronic obstructive pulmonary disease improves exercise capacity.

Pursed lips breathing (PLB) is used by a proportion of patients with chronic obstructive pulmonary disease (COPD) to alleviate dyspnea. It is also commonly used in pulmonary rehabilitation. Data to support its use in patients who do not spontaneously adopt PLB are limited.

Effect of tripod position on objective parameters of respiratory function in stable chronic obstructive pulmonary disease.

Objective: To examine changes in respiratory dynamics in patients with chronic obstructive pulmonary disease (COPD) sitting leaning forward with hands supported on the knees (tripod position), a posture frequently assumed by patients in respiratory distress.

Methods: Spirometry, maximal inspiratory and expiratory pressures (MIP and MEP) generated at the mouth, and diaphragmatic excursion during tidal and vital capacity maneuver breathing measured by B-mode ultrasonography were studied in 13 patients with stable COPD in sitting, supine and tripod positions.

Results: Mean +/- SD age of patients was 52.

Derivation of a prognostic equation to predict in-hospital mortality and requirement of invasive mechanical ventilation in patients with acute exacerbation of chronic obstructive pulmonary disease.

Objective: Predicting in-hospital mortality and formulating a scoring system derived from predictors of mortality may aid prognostication.

Methods: One hundred and fifty-one consecutive patients admitted with a diagnosis of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) were followed to discharge or death in hospital stay. Secondary variables studied were duration of hospital stay, and need for and duration of mechanical ventilation (MV).

Non-pharmacological management of hypertension.

Hypertension is a silent killer. Indians are racially predisposed to cardiovascular disease and the increasing burden of hypertension has only added to the problem. Economic constraints and the allure of additional benefits without adverse effects have made lifestyle modifications an attractive proposition in developing and developed countries alike.
