ABSTRACT
Background: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has considerable cardiovascular risk. Various cardiovascular diseases are common during exacerbations. Both diseases share several similarities such as older age of the patient, smoking as a common risk factor and symptoms of exertional dyspnea. Knowledge regarding the magnitude of underlying cardiovascular diseases during AECOPD is limited. Authors performed this study to assess the presence of different associated cardiovascular diseases (CVDs) in patients hospitalized for AECOPD and its effect on the outcome.Methods: It was a prospective observational study involving 436 patients of AECOPD divided to Group 1 (AECOPD with CVD- 137 (31.4%) patients) and Group 2 (AECOPD without CVD 299 (68.6%) patients). All the patients were subjected to full history taking, clinical examination, chest X-ray, spirometry, ECG and echocardiography.Results: COPD patients in exacerbation with CVD, were significantly more likely to have longer duration of hospital stay (p < 0.0001), high CRP level (p<0.001), more frequent mechanical ventilations (p < 0.001), two or more exacerbations per year (p <0.0001) and the mortality was (p<0.0001). Also, they have GOLD grade III/IV severe (43.5%) and very severe (19.5%) air flow limitation. The high percentage of them had (64.8%) pulmonary hypertension, (37.3%) systemic arterial hypertension, (31.5%) arrhythmia, (27.8%) ischemic heart diseases and (21.3%) heart failure.Conclusions: The prevalence of cardiovascular diseases (CVD) in patients hospitalized for COPD was high. Age, sex and CVD trends, as well as life style changes, should be considered when prevention and control strategies are formulated.
ABSTRACT
Abstract Objective: The study aimed to identify the factors affecting the prognosis of post myocardial infarction (MI) ventricular septal rupture (VSR) and to develop a protocol for its management. Methods: This was a single center, retrospective-prospective study (2009-2014), involving 55 patients with post MI VSR. The strengths of association between risk factors and prognosis were assessed using multivariate logistic regression analysis. The UNM Post MI VSR management and prognosis scoring systems (UPMS & UPPS) were developed. Results: Thirty-day mortality was 52.5% (35% in the last 3 years). Twenty-eight (70%) patients underwent concomitant coronary artery bypass grafting. Residual ventricular septal defect was found in 3 (7.5%) patients. The multivariate analysis showed low mean blood pressure with intra-aortic balloon pump (OR 11.43, P=0.001), higher EuroSCORE II (OR 7.47, P=0.006), higher Killip class (OR 27.95, P=0.00), and shorter intervals between MI and VSR (OR 7.90, P=0.005) as well as VSR and Surgery (OR 5.76, P=0.016) to be strong predictors of mortality. Concomitant coronary artery bypass grafting (P=0.17) and location (P=0.25) of VSR did not affect the outcome. Mean follow-up was 635.8±472.5 days and 17 out of 19 discharged patients were in NYHA class I-II. Conclusion: The UNM Post-MI VSR Scoring Systems (UPMS & UPPS) help in management and prognosis, respectively. They divide patients into 3 groups: 1) Immediate Surgery - Patients with scores of <25 require immediate surgery, preferably with extracorporeal membrane oxygenation support, and have poor prognosis; 2) Those with scores of 25-75 should be managed with "Optimal Delay" and they have intermediate outcomes; 3) Patients with scores of >75 can undergo Elective Repair and they are likely to have good outcomes.
