A patient ill with essential arterial hypertension had a hypertensic crisis that resulted in an attack of cardiac asthma. What is the leading mechanism of cardiac insufficiency in this case?

Answer options

1. Heart overload caused by high pressure
2. Heart overload caused by increased blood volume
3. Blood supply disturbance
4. Absolute coronary insufficiency
5. Myocardium damage

Explanation

Increased blood pressure and hypertensive crisis lead to an increase in workload on the heart, increasing the normal pressure the heart is meant to pump against. This increase in workload can lead to cardiac insufficiency as a result of the excessively increased blood pressure.
