One of the most serious types of heart disease is pulmonary heart disease which is characterized by a change in the right ventricle structure which causes respiratory disorders. About 1 million people are affected by pulmonary heart disease every year. Many factors can increase the risks for pulmonary heart disease, among them there is smoking, bad sleeping habits and obesity. In fact, pulmonary heart disease is a condition when pulmonary pressure in the arteries is elevated and there is a lung which in combination cause heart failure on the right side. The good news is that nowadays there are new treatments which improve the prognosis for treating pulmonary heart disease. Pulmonary edema can happen with no reason, although the regular problem is a long term untreated heart disorder. The disease causes chronic changes in pulmonary artery, chest cavity and lungs, which provokes a lung circulation obstruction. The changes lead to high pressure in the artery and enlarge the right heart half. Pulmonary heart disease strikes if the flow of blood to the lungs is blocked because of lung dysfunction. This elevates the pressure on the heart and lungs which have to work harder. Eventually this causes pulmonary heart disease. Coronary heart disease is a condition when a plaque is formed in the artery which pumps blood to the heart. With time the disease aggravates, the symptoms are mostly non-existent till the disease manifests in a heart attack. This condition might cause congestive heart failure, with respiration worsening caused by pulmonary edema, legs swelling because of peripheral edema and congestive hepatomegaly. The condition is treated with diuretics, at times nitrates and rarely with inotropes to enhance heart contractility. This form of heart disease is most common, and it takes the first place in the causes of heart attacks. All in all, coronary heart disease describes the heart damage caused by decreased blood supply. Fatty deposits are stored in the blood vessels which are supposed to bring blood to the heart muscles. As a result, the blood vessels narrow dramatically. Signs of the disorder can be different, basing on the extent of lung involvement. Simple embolism can produce dyspnea, persistent cough, tachypnea, hemoptysis and pleuritic pain. Pulmonary heart disease can develop complications; the most common one is congestive heart failure. It is very serious as it badly responds to treatments. The right half of the heart grows in size attempting to overcome the resistance to the blood flow between lungs and heart. This eventually causes heart failure. No matter what causes the interruption of regular blood flow between the lungs and heart, first of all, it should be dealt with. Infections are to be managed as soon as possible. If heart failure occurs, still there is hope in case the patient is treated properly.
