  "abstract": "Introduction Low BP is common in HF patients and it’s often a consequence of HF disease-modifying therapies. Current clinical practice accepts low systolic BP (SBP) unless clear hypotension symptoms are evident, raising concerns about risks such as falls, particularly in elderly patients. Symptoms often attributed to HF, such as fatigue and general malaise, may instead be linked to hypotension. Clinic BP measurements may not reflect routine BP values, potentially exposing patients to lower-than-recognized BP levels. In particular, aggressive BP lowering in frail patients may exacerbate complications without cardiovascular benefit. Literature suggests low BP prevalence in chronic HF is 10–15%, though recent studies report rates up to 40% in HFrEF patients on suboptimal DMT where hypotension represented the limiting factor to further titration. Hypotension, especially daytime SBP <90 mmHg, is linked to increased incidence/faster progression of cognitive impairment, renal dysfunction, reduced autonomy, higher hospitalisation and mortality rates. This study is designed to assess the prevalence of significant hypotension in stable HF patients using clinic and ambulatory BP monitoring (ABPM), proving additional information on the accuracy of these tools.Methods A total of 116 stable HF patients with no symptoms indicative of systemic hypotension have undergone clinic BP assessment and 24-hour ABPM ( table 1). Significant hypotension was defined as ≥ 1 episode of daytime SBP <90 mmHg (day-time dipping) or nocturnal SBP <80 mmHg (night-time dipping).Results Daytime dipping has been noted in 56 (48%) patient. Among these, 27 (48%) also exhibited nocturnal dipping. 5 patients showed only nocturnal dipping events. A comparison of the average SBP in clinic and on ABPM is reported below.Conclusion This study suggests a significant presence of hypotension, even in those without obvious symptoms. It also pointed out the inconsistencies between clinic and ABPM readings, suggesting that clinic measurements might not reflect patients’ true BP.Abstract 46 Table 1Demographics and clinical featuresAbstract 46 Table 2Result table – average SBP in daytime dippers",
