Background: Several studies have shown an association between increased red blood cell distribution width (RDW) and adverse outcomes in various acute diseases. Small studies have suggested that RDW is a useful predictor of acute pancreatitis severity.

Objectives: To determine the association between RDW at admission and early mortality in acute pancreatitis. To assess whether RDW adds to the predictive ability of the Glasgow Imrie Score.

Methods: In this observational study, we included all adult patients admitted with a primary diagnosis of acute pancreatitis between January 2008 and June 2021. Patients were divided into two groups according to RDW: normal RDW (RDW ≤ 14.5%) and elevated RDW (RDW > 14.5%).

Results: Within 30 days of admission, 29/438 patients (6.6%) with increased RDW and 20/1250 patients (1.6%) with normal RDW had died: univariate analysis (odds ratio 4.6, 95% confidence interval 2.45–7.9, P < 0.001), fully adjusted model (odds ratio 3.29, 95% confidence interval 1.75–6.26, P < 0.001). We calculated receiver operating characteristic curve (ROC) for RDW alone, Glasgow Imrie Score alone, and a combination of Glasgow Imrie Score with RDW. We assessed their ability to predict 30-day mortality. Area under the ROC curve (AUC) of RDW alone was 0.671 and Glasgow Imrie Score AUC was 0.682; Glasgow Imrie Score plus RDW had an AUC of 0.769.

Conclusions: In patients with acute pancreatitis, elevated RDW at admission was independently associated with increased 30-day mortality. The addition of RDW to a pancreatitis prognostic tool such as the Glasgow Imrie Score improves its predictive ability.

Background: Current guidelines for the treatment of heart failure with reduced ejection fraction (HFrEF) are based on studies that have excluded or underrepresented older patients.

Objectives: To assess the value of guideline directed medical therapy (GDMT) in HFrEF patients 80 years of age and older.

Methods: A single-center retrospective study included patients hospitalized with a first and primary diagnosis of acute decompensated heart failure (ADHF) and ejection fraction (EF) of ≤ 40%. Patients 80 years of age and older were stratified into two groups: GDMT, defined as treatment at hospital discharge with at least two drugs of the following groups: beta-blockers, angiotensin converting enzyme inhibitor (ACEI), angiotensin receptor blocker (ARB), or mineralocorticoid antagonists; and a personalized medicine group, which included patients who were treated with up to one of these drug groups. The primary outcomes were 90-day all-cause mortality, 90-day rehospitalization, and 3-years mortality.

Results: The study included 1152 patients with HFrEF. 254 (22%) patients who were at least 80 years old. Of the group, 123 were GDMT at discharge. When GDMT group was compared to the personalized medicine group, there were no statistically significant differences in terms 90-day mortality (17% vs. 13%, P = 0.169), 90-day readmission (51 % vs. 45.6%, P = 0.27), or 3-year mortality (64.5% vs. 63.3%, P = 0.915).

Conclusions: Adherence to guidelines in the older adult population may not have the same effect as in younger patients who were studied in the randomized clinical trials. Larger prospective studies are needed to further address this issue.

Background: Multi-detector computed tomography has advanced enormously and now enables non-invasive evaluation of coronary arteries as well as cardiac anatomy, function and perfusion. However, the role of cardiac MDCT[1] is not yet determined in the medical community and, consequently, many clinically unnecessary scans are performed solely on a self-referral basis.

Objectives: To prospectively evaluate the role of a cardiologist consultation and recommendation prior to the scan, and the influence on the diagnostic yield of cardiac MDCT.

Methods: In our center, a CT service was initiated, but with the prerequisite approval of a cardiologist before performance of the CT. Each individual who wanted and was willing to pay for a cardiac CT was interviewed by an experienced cardiologist who determined whether cardiac MDCT was the most appropriate next test in the cardiovascular evaluation. Subjects were classified into three groups: a) those with a normal or no prior stress test, no typical symptoms and no significant risk factors of coronary artery disease were recommended to perform a stress test or to remain under close clinical follow-up without MDCT; b) those with an equivocal stress test, atypical symptoms and/or significant risk factors were allowed to have cardiac MDCT; and c) those with positive stress test or clinically highly suspected CAD[2] were advised to go directly to invasive coronary angiography. CT findings were categorized as normal CAD (normal calcium score and no narrowings), < 50% and > 50% CAD.

Results: A total of 254 people were interviewed, and in only 39 cases did the cardiologist approve the CT. However, 61 of the 215, despite our recommendation not to undergo CT, decided to have the scan. Assessment of the 100 cases that underwent MDCT showed a statistically significant better discrimination of significant CAD, according to the cardiologist’s recommendation: MDCT not recommended in 3/54 (6%) vs. MDCT recommended in 12/39 (31%) vs. recommended invasive coronary angiography in 4/7 (57%) (P < 0.001).

Conclusions: Detection of coronary calcification, as well as MDCT angiography can provide clinically useful information if applied to suitable patient groups. It is foreseeable that MDCT angiography will become part of the routine workup in some subsets of patients with suspected CAD. Selection of patients undergoing MDCT scans by a cardiologist improves the ability of the test to stratify patients, preventing unnecessary scans in both high and low risk patients
