A patient has a diagnosis of left ventricular failure. Which of the following signs and symptoms are associated with left ventricular failure?

Acute respiratory distress syndrome (ARDS) is the most likely diagnosis based on the patient's symptoms and test results. ARDS is a serious condition that can develop in response to a variety of lung injuries, including pneumonia, sepsis, and trauma. The hallmark of ARDS is diffuse alveolocapillary injury, which leads to decreased lung compliance, hypoxemia, and respiratory distress. The symptoms of ARDS typically develop rapidly and include dyspnea, rapid, shallow breathing, inspiratory crackles, and hypoxemia. Treatment for ARDS typically involves supportive care, including oxygen therapy, mechanical ventilation, and treatment of the underlying cause of the lung injury.

Modifiable risk factors for coronary artery disease (CAD) are those that can be changed or controlled to reduce the risk of developing CAD. These include high blood pressure, high cholesterol levels, smoking, physical inactivity, unhealthy diet, and obesity. High HDL (high-density lipoprotein) is actually a desirable factor, as it is known as the "good cholesterol" and helps to remove excess cholesterol from the body. Orthostatic hypotension, or a drop in blood pressure upon standing, is not considered a modifiable risk factor for CAD.
