Question

A Patient X., who suffers from arterial hypertension, came to clinic, he complains of periodic inspiratory short breath, especially by physical activity. Few days ago appeared the attack of inspiratory short breath with death anxiety. The ambulance was called, diagnose was “cardiac asthma”. On examination: arterial pressure: 155/120 millimeters of mercury, by roentgenoscopy- dilatation of left ventricle of heart. What forms of heart activity pathology has a patient? What caused its development? Is it connected with ventricular overload? What? Overload with volume or pressure? What is a trigger mechanism of contractile myocardial function by its overload?

Expert Solution

Step 1: Analyzing the case study

This case study involves Patient X, who has a history of arterial hypertension and presents with symptoms of periodic inspiratory shortness of breath, particularly during physical activity. Recently, the patient experienced an episode of severe shortness of breath accompanied by a sense of impending doom, leading to a diagnosis of "cardiac asthma". Examination findings included elevated blood pressure and roentgenoscopic evidence of left ventricular dilation. The following discussion will explore the potential heart pathology, its cause, its connection with ventricular overload, and the trigger mechanism of contractile myocardial function in the context of overload.
