Dr. Bereliani adds that heart valves can get damaged due to infection, which he says can come from illicit IV drug use or a bacterial tooth infection. It’s also possible for the body’s immune ...
Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
This can subsequently induce necrotic cell death, fibrosis, and mitochondrial dysfunction. [6] This has been demonstrated in animal studies. Protein Kinase C (PKC) is an intermediate molecule in the signalling pathway and mice lacking PKC shown resistance to heart failure compared to mice overexpressing PKC which shown heart dysfunction.

Atelectasis occurs when distending pressure of the alveolus is overcome by surface tension of fluid within the alveolus. Repeated atelectasis and re-inflation leads to atelectotrauma . Atelectotrauma , atelectrauma , cyclic atelectasis or repeated alveolar collapse and expansion ( RACE ) are medical terms for the damage caused to the lung by ...
The heart valve changes seen with moderate and intermittent use can result in permanent damage and life-threatening heart problems if use of the causative drug is increased or continued, however longitudinal studies of former patients suggest that the damage will heal over time to some extent at least.

Chest x-ray demonstrating severe atelectasis or collapse of the right lung and mediastinal shift towards the right. Atelectasis is the partial collapse of a lung that is reversible. There are numerous etiologies, including post-operative atelectasis, surfactant deficiency, mucus plugging, and foreign body aspiration.
Overdistension of alveoli and cyclic atelectasis (atelectotrauma) are the primary causes for alveolar injury during positive pressure mechanical ventilation.Severe injury to alveoli causes swelling of the tissues (edema) in the lungs, bleeding of the alveoli, loss of surfactant (decrease in lung compliance) and complete alveoli collapse ().
The heart can be seen in the center. The thoracic cavity is the space inside the chest that contains the lungs, heart, and numerous major blood vessels. On each side of the cavity, a pleural membrane covers the surface of lung ( visceral pleura ) and also lines the inside of the chest wall ( parietal pleura ).
