the correlation between the improvement of dyspnoea condition and the decrease b-line counts in the observation of nitrate therapy for acute heart failure

Acute heart failure is common in emergency department. Patients with acute heart failure generally come with dyspnoea. Diagnosing acute heart failure should be done rapidly so that therapy can be given immediately. The use of ultrasound for diagnosis is increasingly common. With a sensitivity exceeding 90% to assess alveolar interstitial syndrome to diagnose acute heart failure, it is expected that B-line in lung ultrasound can be used to monitor acute heart failure therapy objectively. Therapy of acute heart failure includes oxygenation with continuous positive airway pressure, nitrates, and diuretics. Monitoring of this therapy in Dr. Saiful Anwar general hospital emergency department is still based on subjective improvement of dyspnoea, while ultrasound is rarely used. This article is to analyse the correlation between dyspnoea improvement and decrease of B-line count in the monitoring of acute heart failure therapy. The research was an observational analytic, cross-sectional study to analyse the correlation between dyspnoea improvement with decrease of B-lines count in the monitoring of acute heart failure therapy. As many as 45 subjects were included in this study. The correlation between dyspnoea improvement and decrease of B-Line count in minute 0 to minute 15 using independent samples t-test showed no significant result (p= 0.711). The correlation between dyspnoea improvement and decrease of B-Line count in minute 15 to minute 30 using Kruskal-Wallis test also showed no significant result (p= 0.153). The results find that there was no significant correlation between dyspnoea improvement and decrease of B-line counts in the initial 30 minute in monitoring of acute heart failure therapy.
