Chronic Obstructive Pulmonary Disease in Patients Presenting with Heart Failure
Notice bibliographique
Résumé
IntroductionCongestive heart failure befalls in which heart becomes unable to pump the apt amount of blood and oxygen 1 required to meet the demands of the body .It is a major public health issue causing a significant number of premature morbidity and mortality and reduced quality 2 of life all around the globe .According to 2021 statistical report of American Heart Association (AHA), the prevalence of heart failure is estimated to be 6 million which 3 is around 1.8% of the total population of United States .Other reports showed the prevalence of heart failure in Europe to be 1-2% and in U.S. and Canada to be 1.5-4 1.9% .In Pakistan, the incidence of HF was reported as 14.75% in 2008, 19.32% in 2009 and 22.87% in 5 2010 out of total admissions into the cardiology unit.Chronic inflammatory condition causing persistent limitation of airflow from the lungs may be called as 6 COPD .It is also a serious public health concern, and mortality caused by COPD is expected to increase greatly in future.In 2019, the prevalence of COPD was estimated to be around 10.3% among individuals aged 30-79 years in low and middle income countries.In South Asian countries, the reported COPD cases were approximately 7 109.3 million .In Pakistan, the estimated prevalence of 8 COPD is 2.1% in individuals ages 40 years or more . 9Gold standard for the diagnosis of COPD is spirometry .HF and COPD seem to coexist more frequently than expected from their separate prevalence, leading to poor prognosis and increased mortality.Both conditions share common risk factors such as advanced age and AbstractObjective: To determine the frequency of chronic obstructive pulmonary disease in patients presenting with Congestive Heart Failure.Methods: This cross sectional study was undertaken in Department of Internal Medicine, Combined Military Hospital, Lahore, from September 2015 to March 2016.100 cases fulfilling inclusion criteria were enrolled in study through purposive sampling technique.Pulmonary function test was performed in patients by using spirometry to measure their forced vital capacity (FVC), forced expiratory volume in the first second (FEV1) and FVC to FEV1 ratio.If the levels of spirometry assessment were low, then the patient was labeled as having poor pulmonary function.All the data was entered and analyzed utilizing SPSS version 26.Results: In this study, the mean age of the patients was 60.31±11.08years.There were 64(64.0%)males and 36(36.0%)females.The male to female ratio was 1.7:1.The mean values of FVC, FEV1, and FVC/FEV1 ratio of the patients were 80.30±7.26,59.75±5.99,and 0.75±0.102,respectively.The COPD was observed in 33(33%) patients with CHF.There was no statistically significant difference between the age group and gender with COPD (p>0.05). Conclusion:The prevalence of COPD is substantial in patients admitted with CHF (33.0%).Therefore, spirometry ought to be done earlier in CHF patients to timely diagnose COPD, if present.So that early and appropriate therapeutic strategies can be planned to improve the prognosis and quality of life in such patients.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
