The typical symptoms of acute heart failure include sudden severe difficulty breathing, increased respiratory rate, and patients generally presenting a forced sitting position, with pale, grayish complexion and cyanotic lips. They often have profuse sweating, restlessness, frequent coughing, and coughing up pink frothy sputum. The condition can be critical, leading to consciousness disturbances due to lack of oxygen. Once acute heart failure occurs, active treatment is essential. The most common clinical approaches include strengthening the heart, diuresis, and vasodilation for symptomatic active management.
