Despite compensatory mechanisms, the heart may be unable to maintain an adequate cardiac output. Decreased blood flow to the kidneys continues to stimulate sodium and water reabsorption, leading to hypervolemia, increased workload on the heart, and congestion in the pulmonary and systemic circulations. Since these hemodynamic changes occur at different times, the signs and symptoms can vary.

Anthracosis and silicosis are major industrial problems in developing but industrialized nations since a large number of workers are engaged in mining in many states of such countries. Prolonged exposure to cola dust causes anthracosis among miners. These particles give a black color to the lesions.

Investigation into a possible exposure to asbestos in the patient's past is pertinent. Symptoms of asbestosis usually appear after a latency period of 20 or so years. Dyspnea upon exertion is the most common and prominent symptom exhibited by patients. Patients may also report a non-productive cough, wheezing, and nonspecific chest pain. Fatigue and weight loss are also common complaints. As the disease progresses, the dyspnea worsens as well.


Hypertension is often asymptomatic or cause only proceeds uncharacteristic complaints. It is typically occurring in the morning as a headache, which can be reduced by increasing the bed head end. Other possible symptoms include dizziness, nausea, nosebleeds (epistaxis), fatigue and insomnia. At high blood pressure, shortness of breath can occur (dyspnea) with exertion, angina pectoris, and visual disturbances. Arterial hypertension may also long asymptomatic (without symptoms).

In men or in postmenopausal ladies with iron deficiency, GI bleeding is usually the trigger. Blood reduction in this case may be because of to relatively benign problems, this kind of as peptic ulcer, arteriovenous malformations, or angiodysplasia (little vascular abnormalities along the intestinal walls). More severe causes are inflammatory bowel disease or malignancy.

Many times angina is the worst during moments of exertion. This is because the demand for oxygenated blood increases when heart rate increases. If the coronary arty is narrowed then it will have difficulty supplying the blood as fast as the heart needs it. The result is angina or in some cases dyspnea equivalent angina. The only way to relieve the angina is through resting to bring the heart rate back to normal and lower the demands for oxygenated blood.

Dyspnea is breathing perceived by a affected individual as both uncomfortable or anxiety-provoking and disproportionate towards the degree of activity. The affected individual at first notices dyspnea only with exertion but may progress to experience dyspnea at rest. In severe cases, pulmonary edema may be accompanied by edema fluid in the sputum and can trigger acute respiratory failure.

If the patient coughs and expels sputum for about three months in a year for two consecutive years, the patient might be suffering from chronic bronchitis. Chronic bronchitis is also characterized by excessive production of mucus, cough, and dysnea, or difficulties in breathing while exerting oneself physically.

The earliest sign is frequently a chest radiograph showing an improve in the caliber of the upper lobe vessels ("pulmonary vascular redistribution") and fluid accumulating within the perivascular and peribronchial spaces ("cuffing"). It may also show Kerley B lines, which represent fluid within the interlobular septa.

Leg cramps during exercise might be caused by dehydration. It is important to drink a lot of fluid during exercise. Leg cramps occur when the muscle suddenly and forcefully contracts. The most common muscles to contract in this manner are muscles that cross two joints. Leg cramps during walking might be an indication of heart disease caused by arteries in your leg being clogged up by cholesterol in result of not enough oxygen being delivered to the cells in your leg.

Actual true forms of asthma are often characterized by hyper-activity in the airways and are accompanied by a reversible bronchoconstriction, as compared to chronic bronchitis, where the symptoms are characterized by excessive mucus and inflammation of the airway.

This sometimes takes place when the heart muscle is feeble due to illness or stress. There are numerous first coronary artery sicknesses but congestive heart failure, sometimes a secondary illness, has the least wealthy diagnosis. Myocardial infarction, harsh anemia, and renal collapse customarily follows a myocardial infarction. Different effects on the body can be seen when the heart is not able to work correctly as all sides of the heart has a different function.

The lungs are in the inflated position occupying the whole of the pleural cavity. Since the elastic tissue is damaged, the lungs lose their elasticity and they fail to collapse when the chest is opened during autopsy. The diaphragm is depressed and respiratory excursions are diminished. The alveoli are over-distended. The septa rupture and neighboring alveoli coalese to form air cysts.

Before a full-blown asthma attack, there are usually early signs and symptoms you should be able to easily recognize. Irritation of the nose and throat, thirst, and the increased need to urinate are all common symptoms that may occur before an asthma attack. Each person has his or her own peculiar pattern of early symptoms, and most often, these symptoms progress to a severe respiratory distress episode if not properly treated.
