Cardiovascular comorbidity is the main reason for hospital admission and mortality in COPD patients, especially in mild-moderate stage of the disease. Aim: To evaluate both right ventricle (RV) and left ventricular (LV) function in patient with COPD by echocardiography and its correlation with the severity of the disease. Material & Method: 60 patients with COPD and thirty healthy subjects were assessed by echocardiography and pulmonary function test. Results: LV parameters were similar in both groups, while RV parameters were significantly higher in COPD patients. Mild, moderate, severe and very severe COPD were seen in 6.66%, 35%, 36.67%, 21.67% respectively, with mean forced expiratory volume in 1s (FEV1%pred) 47.52±17.92%. RV systolic dysfunction in moderate, severe and very severe COPD was present in 47.61%, 59.09%, 53.84% to the number of patients in that stage accordingly. Pulmonary hypertension (PH) was observed in 33.33% of all patients. The presence in different stages was 23.8%, 41%, 46.15%, in moderate, severe and very severe COPD respectively. Impairment of LV diastolic function in moderate, severe and very severe COPD was present in 14.28%, 54.54%, 23.07%, according to the number of patients in that stage. Enlarged left atrium was measured in 42%. Tricuspid regurgitation was the most frequent valvular abnormality, observed in 66.67%. LV systolic function was significantly higher in healthy subjects compared to COPD patients 63.73±1.90% vs. 57.43±6.93%. PH was not detected in the healthy subjects. Conclusion: There is high prevalence of PH, RV systolic dysfunction and tricuspid regurgitation in COPD patients and severity increases with level of severity of COPD.

Adenocarcinoma of the lung is the most widely recognized kind of lung disease, and like different types of lung malignant growth, it is described by particular cell and sub-atomic features. It is named one of a few non-little cell lung tumors (NSCLC), to recognize it from little cell lung malignancy which has an alternate conduct and anticipation. Lung adenocarcinoma is additionally grouped into a few subtypes and variants. The signs and manifestations of this particular kind of lung malignant growth are like different types of lung disease, and patients most regularly grumble of relentless hack and brevity of breath.
Adenocarcinoma is increasingly normal in patients with a background marked by cigarette smoking, and is the most well-known type of lung disease in more youthful ladies and Asian populaces. The pathophysiology of adenocarcinoma is confounded, however for the most part follows a histologic movement from cells found in solid lungs to particularly dysmorphic, or sporadic, cells. There are a few unmistakable sub-atomic and hereditary pathways that add to this movement. In the same way as other lung malignant growths, adenocarcinoma of the lung is regularly best in class when of finding. When a sore or tumor is related to different imaging modalities, for example, figured tomography (CT) or X-beam, a biopsy is required to affirm the conclusion.
Treatment of this lung disease depends on the particular subtype and the degree of spread from the essential tumor. Careful resection, chemotherapy, radiotherapy, directed treatment and immunotherapy are utilized in endeavor to annihilate the harmful cells dependent on these components
Signs and Symptoms
Most of patients who are determined to have lung malignant growth typically present with privately progressed or metastatic malady. Just around 33% of patients have stage I infection when diagnosed. The side effects that the patient displays normally mirror the degree of the malignant growth's spread. Lung tumors that are found early may cause indications limited to the respiratory framework. Be that as it may, lung malignancy that is propelled will make patients experience extra signs and indications auxiliary to the disease spreading to other organ systems. In request of most elevated recurrence, the most widely recognized indications of lung malignant growth include:
• hack that doesn't leave or deteriorates
• weight reduction
• dyspnea (brevity of breath or trouble relaxing)
• chest torment, which might be exasperated by profoundbreathing, hacking, or snickering hemoptysis (hacking upblood or rust-shaded phlegm)
• bone agony
• for the most part feeling drained or powerless
• predominant vena cava block facial, neck, upper middleexpanding. This is brought about by pressure of vasculature bythe lung tumor that confines blood come back from the upperbody.
• dysphagia (inconvenience gulping or the impression thatsomething is trapped in the throat) and roughness
• new beginning of wheezing without history of asthma
Clinicians ought to have an elevated level of doubt for lung malignant growth, particularly in patients with a smoking history. Patients with repeating or unresolving lung contaminations (for example bronchitis and pneumonia) that are inert to anti-toxins ought to likewise be additionally assessed for lung malignant growth. In nonsmokers, ladies and East Asians are bound to give side effects of a basic lung malignancy at more youthful ages. Importantly, a considerable lot of these signs are regularly because of different causes which are not cancer. A point by point clinical history ought to be gotten from every patient to decide the significance of further symptomatic workup and the board.
Hazard factors: As indicated by the Nurses' Health Study, the danger of aspiratory adenocarcinoma increments significantly after a long length of tobacco smoking: smokers with a past smoking span of 30–40 years are more than twice as prone to create lung adenocarcinoma contrasted with never-smokers (relative danger of around 2.4); a term of over 40 years expands relative hazard to 5.
This malignant growth as a rule is seen incidentally in the lungs, instead of little cell lung disease and squamous cell lung disease, which both will in general be all the more halfway located,in spite of the fact that it might likewise happen as focal lesions. For obscure reasons, it regularly emerges according to fringe lung scars. The current hypothesis is that the scar likely happened optional to the tumor, instead of causing the tumor. The adenocarcinoma has an expanded frequency in smokers, and is the most well-known kind of lung malignant growth seen in non-smokers and women. Deeper inward breath of tobacco smoke brings about fringe injuries that are regularly the situation in adenocarcinomas of the lung. For the most part, adenocarcinoma develops more gradually and structures littler masses than the other subtypes. However, it will in general metastasize at a beginning period.
A finding of lung malignancy might be associated on the premise with run of the mill side effects, especially in an individual with smoking history. Manifestations, for example, hacking up blood and accidental weight reduction may provoke further examination, for example, clinical imaging.
