Cirrhotic cardiomyopathy: Predictors of major adverse cardiac events and assessment of reversibility after liver transplant.

BACKGROUND: Major adverse cardiac events (MACE) are a leading cause of morbidity and mortality after orthotopic liver transplantation (OLT). Cirrhotic cardiomyopathy (CCM), initially described in 2005 and revised in 2019, is a source of MACE in patients after OLT. We sought to identify CCM-related predictors of MACE at one-year follow-up after OLT and assess for reversibility of CCM post-OLT. METHODS: This is a retrospective study of adult patients who underwent OLT between 2009 and 2019. All patients had transthoracic echocardiography pre-and post-OLT. Patients with a left ventricular ejection fraction <50 % pre-OLT were excluded. MACE was defined as death, myocardial infarction, congestive heart failure hospitalization, or cardiac arrest. RESULTS: In total, 131 patients were included in this study, of whom 103 and 23 patients met the 2005 and 2019 criteria, respectively. During the follow-up period, 42 patients had MACE and these patients were more likely to have ascites (p = 0.003), hepatorenal syndrome (p = 0.019), and CCM per 2005 criteria (p = 0.023). There were no significant differences between pre-OLT CCM per 2019 criteria (19 % vs 17 %, p = 0.758) or MELD-Na score (21.24 vs 19.40, p = 0.166) for MACE post-OLT. Per the 2005 criteria, 35 of 103 patients recovered and these patients were less likely to have MACE post-OLT (p = 0.012). Per the 2019 criteria, 13 of 23 patients recovered post-OLT but this low number precluded further statistics. CONCLUSION: The 2005 Montreal criteria for CCM were an independent predictor of MACE at one-year follow-up post-OLT while the 2019 CCC criteria for CCM were not. In addition, the 2005 Montreal criteria were more prevalent when compared to 2019 CCC criteria. Finally, the 2005 Montreal criteria were reversible post-OLT 34 % of the time compared to the 2019 CCC criteria which were reversible 57 % of the time.

Recurrent Parotid Adenocarcinoma Presenting as Diffuse Myocardial Metastatic Disease.

A 64-year-old man who had undergone treatment for left parotid adenocarcinoma presented with progressive exertional shortness of breath. Evaluation revealed metastatic invasion of the myocardium as a rare presentation of recurrent parotid adenocarcinoma. This case highlights the importance of using multimodal imaging methods in diagnostic evaluation and a collaborative multidisciplinary approach in managing patient care.

Prognostic utility of blood pressure-adjusted global and basal systolic longitudinal strain.

Assessment of global longitudinal systolic strain (GLS) and longitudinal systolic strain of the basal segments (BLS) has shown prognostic value in cardiac disorders. However, strain is reduced with increased afterload. We assessed the prognostic value of GLS and BLS adjusted for afterload. GLS and BLS were determined in 272 subjects with normal ejection fraction and no known coronary disease, or significant valve disease. Systolic blood pressure (SP) and diastolic blood pressure (DP) obtained at the time of echocardiography were used to adjust GLS and BLS as follows: strain×SP (mmHg)/120 mmHg and strain×DP (mmHg)/80 mmHg. Patients were followed for cardiac events and mortality. The mean age was 53±15 years and 53% had hypertension. There were 19 cardiac events and 70 deaths over a mean follow-up of 26±14 months. Cox analysis showed that left ventricular mass index (P=0.001), BLS (P<0.001), and DP-adjusted BLS (P<0.001) were independent predictors of cardiac events. DP-adjusted BLS added incremental value (P<0.001) to the other two predictors and had an area under the curve of 0.838 for events. DP (P=0.001), age (P=0.001), ACE inhibitor use (P=0.017), and SP-adjusted BLS (P=0.012) were independent predictors of mortality. SP-adjusted BLS added incremental value (P=0.014) to the other independent predictors. In conclusion, DP-adjusted BLS and SP-adjusted BLS were independent predictors of cardiac events and mortality, respectively. Blood pressure-adjusted strain added incremental prognostic value to other predictors of outcome.
