Prevalence of chronic obstructive pulmonary disease among patients with systemic arterial hypertension without respiratory symptoms

Abstract

BackgroundThe diagnosis of chronic obstructive pulmonary disease (COPD) is often delayed until later stages of the disease. The purpose of the present study was to determine the prevalence of COPD among adults on treatment for systemic arterial hypertension independently of the presence of respiratory symptoms.MethodsThis cross-sectional study included adults aged ≥40 years with tobacco/occupational exposure and systemic arterial hypertension diagnosed at three Primary Health Care facilities in Goiania, Brazil. Patients were evaluated using a standardized respiratory questionnaire and spirometry. COPD prevalence was measured considering the value of forced vital capacity and/or forced expiratory volume in 1 second <0.70.ResultsOf a total of 570 subjects, 316 (55%) met inclusion criteria and were invited to participate. Two hundred and thirty-three (73.7%) patients with arterial hypertension reported at least one respiratory symptom, while 83 (26.3%) reported no respiratory symptoms; 41 (17.6%) patients with arterial hypertension and at least one respiratory symptom, and 10 (12%) patients with arterial hypertension but no respiratory symptoms were diagnosed with COPD (P=0.24). The prevalence of COPD in people with no previous COPD diagnosis was greater among those with no respiratory symptoms (100%) than among those with respiratory symptoms (56.1%) (P=0.01).ConclusionOur findings suggest that regardless of the presence of respiratory symptoms, individuals aged ≥40 years with tobacco/occupational exposure and arterial hypertension may benefit from spirometric evaluation.

Prevalence of Chronic Obstructive Pulmonary Disease in Patients With Coronary Heart Disease and Arterial Hypertension

“…Especially, the prevalence of combined course among men and women in 2007 was 7,39 % and 9,35 % respectively, in 2008 -11,2 % and 10,7 % respectively, in 2009 -12,7 % and 10,9 % respectively [11].…”

“…It is argued by the data about the influence of broncholithus on heart rate, electrolytic changes. So, it is important to elaborate the simple available screening methods that allow to select patients for further functional examination with high reliability degree [11,[20][21][22]. This very aim is set in our work.…”

“…Arterial hypertension is registered with frequency 15-20 % among adult population of the world and 30-60 % among patients of elder age group [8,9]. Arterial hypertension is an important risk factor of development of complication in cardio-vascular system, injury of target organs that determines morbidity and early invalidism of patients [10,11].…”

Impaired training-induced adaptation of blood pressure in COPD patients: implication of the muscle capillary bed

“… 4 – 6 Identifying the early mechanisms of HTA onset might therefore improve the cardiovascular morbidity and mortality in these patients. 7 Before vascular remodeling occurs, a reduced capillary bed is an early mechanism of HTA. 8 Exercise training studies have confirmed the link between blood pressure (BP) and the capillary bed in both animal models 9 and healthy/hypertensive subjects.…”
