What this trial studies

This study investigates the effectiveness of sildenafil as an additional treatment to dapagliflozin in patients suffering from heart failure with secondary pulmonary hypertension. It aims to compare the outcomes of this combination therapy against the use of dapagliflozin alone. The study will enroll patients diagnosed with heart failure who experience symptoms such as dizziness, heart palpitations, and shortness of breath. The goal is to determine if the combination therapy can provide better relief from symptoms and improve overall heart function.

Who should consider this trial

Good fit: Ideal candidates are adults with established heart failure and secondary pulmonary hypertension who experience specific symptoms related to their condition.

Not a fit: Patients with contraindications to sildenafil or dapagliflozin, or those with pulmonary arterial hypertension from other causes, will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment approach could significantly improve the management of heart failure patients with secondary pulmonary hypertension.

How similar studies have performed: While the combination of these medications has not been extensively tested together, similar studies have shown promise in treating related conditions.
