    Heart attack

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Most heart attacks are caused by a blood clot that blocks one of the coronary arteries. The coronary arteries bring blood and oxygen to the heart. If the blood flow is blocked, the heart is starved of oxygen and heart cells die. The medical term for this is myocardial infarction.

    Hemothorax

    Aortic rupture (a tear in the aorta, which is the major artery coming from the heart) can be seen on a chest x-ray. In this case, it was caused by a traumatic perforation of the thoracic aorta. This is how the x-ray appears when the chest is full of blood (right-sided hemothorax) seen here as cloudiness on the left side of the picture.

    Hemothorax is a collection of blood in the space between the chest wall and the lung (the pleural cavity).

    Hospital-acquired pneumonia

    Pneumonia acquired in the hospital is a very serious infection because the patient's defense mechanisms are often impaired by illness, and the infecting organisms are more dangerous than the ones generally encountered in the community.

    Hospital-acquired pneumonia is an infection of the lungs that occurs during a hospital stay. This type of pneumonia can be very severe. Sometimes it can be fatal.

    Hypovolemic shock

    Hypovolemic is an emergency condition in which severe blood and fluid loss make the heart unable to pump enough blood to the body. This type of shock can cause many organs to stop working.
