Symptoms of heart ( cardiovascular ) disease
CHEYNE-STOKES BREATHING .
Very severe heart failure, and alternatehyperventilation apnea or Cheyne-Stokes breathing may occur.This can also develop in elderly people without obvious heart failure.It associated with depression of the respiratory center, due to poor cardiac and cerebrovascular diseaes. Such ventilation can also be seen after morphine.
SHORTNESS OF BREATH OR DYSPNOEA .
Shortness of breath (dyspnea) is the sensation of difficult or labored breathing. Any disorder, disturb the normal, the delicate balance between oxygen supply and the body need oxygen can cause shortness of breath. It is a common symptom of lung disease, including infection, asthma and allergies. Shortness of breath may also occur in individuals who have a disorder of the respiratory muscles, a nervous system disorder that interferes with breathing, or too few red blood cells carry oxygen to the tissues (anemia). Shortness of breath is also a frequent symptom of heart disease, mainly heart failure (heart failure) and coronary heart disease (CHD).
In heart failure, respiratory distress and escape of fluid into the air spaces of the lungs, a condition known as pulmonary congestion or pulmonary edema. Ultimately, this process is similar to drowning. In the early stages of heart failure, shortness of breath may occur only during physical activity. The worsening heart failure, breathlessness occurs with less activity and, finally, occurs at rest. Shortness of breath at rest occurs mostly when people are lying because they filter the fluid in the lung tissue. This symptom often occurs at night and then called nocturnal dyspnea. When people stand up and turn the legs, gravity causes fluid to accumulate at the base of the lungs, reducing symptoms. Therefore, people with nocturnal dyspnea usually sleep with the support of pillows to keep flat.
In heart disease, shortness of breath usually occurs during physical activity, but people with serious illnesses, which may occur during minimal activity or at rest. Sometimes symptoms suggestive of a cause to the doctor. nocturnal dyspnea that is relieved when sitting with legs dangling and suggests heart failure. Shortness of breath that occurs during physical activity and is accompanied by chest pain to coronary artery disease. Shortness of breath with cough and fever suggests a lung infection. Shortness of breath that seem to be triggered by exposure to something in the environment, such as smoke or animal hair, suggests allergic disease or asthma.
LIMITATION OF PHYSICAL ACTIVITY .
Heart disease can reduce the ability of a person to perform an activity. One way to assess the degree of heart disease is to determine how this capacity is limited. Physicians can use the New York Heart Association (NYHA) functional class system to conduct this assessment. In a mild disease (class I), regular physical activity may be limited. In moderate disease (class II), the ordinary activity causes symptoms, and in moderately severe disease (class III), less the results of ordinary activities of symptoms. In severe disease (class IV), symptoms occur at rest, and any other physical activity that makes them worse. But this system is not foolproof, because even serious heart disease may produce no symptoms, if people reduce their activity to compensate for the disorder.
