Clinical features, management, and short- and long-term outcomes of patients with acute decompensated heart failure: phase I results of the HEARTS database.

The HEart function Assessment Registry Trial in Saudi Arabia (HEARTS) is a national multicentre project, studying clinical features, management, short‐ and long‐term outcomes, and mortality predictors in patients admitted with acute decompensated heart failure (ADHF).

Repeated Monitoring With Transthoracic Echocardiography and Lung Ultrasound After Cardiac Surgery: Feasibility and Impact on Diagnosis

OBJECTIVES Cardiorespiratory complications are common after cardiac surgery and current monitors used to diagnose these are invasive and have limitations. Transthoracic echocardiography and lung ultrasound are noninvasive and frequently improve diagnosis in critically ill patients but have not been reported for routine postoperative monitoring after coronary, valve, and aortic surgery. The aim was to determine whether both repeated postoperative transthoracic echocardiography and lung ultrasound revealed or excluded clinically important cardiac and respiratory disorders compared to conventional monitoring and chest x-ray. DESIGN Prospective observational study. SETTING Tertiary university hospital. PARTICIPANTS Ninety-one patients aged older than 18 undergoing cardiac surgery INTERVENTIONS Postoperative clinical patient assessment for significant cardiac and respiratory disorders by the treating physician was recorded at 3 time points (day after surgery, after extubation and removal of chest drains and at discharge) using conventional monitoring and chest x-ray. After each assessment, transthoracic echocardiography and lung ultrasound were performed, and differences in diagnosis from conventional assessment were recorded. MEASUREMENTS AND MAIN RESULTS Transthoracic echocardiography was interpretable in at least 1 echocardiographic window in 99% of examinations. Transthoracic echocardiography and/or lung ultrasound changed the diagnosis of important cardiac and/or respiratory disorders in 61 patients (67%). New cardiac findings included cardiac dysfunction (38 patients), pericardial effusion (5), mitral regurgitation (2), and hypovolemia (1). New respiratory findings included pleural effusion (30), pneumothorax (4), alveolar interstitial syndrome (3) and consolidation (1). CONCLUSIONS Routine repeated monitoring with cardiac and lung ultrasound after cardiac surgery is feasible and frequently alters diagnosis of clinically important cardiac and respiratory pathology.

Acute heart failure presentations and outcomes during the fasting month of Ramadan: an observational report from seven Middle Eastern countries

Abstract Background: Fasting during the month of Ramadan is practiced by over 1.5 billion Muslims worldwide. It remains unclear, however, how this change in lifestyle affects heart failure, a condition that has reached epidemic dimensions. This study examined the effects of fasting in patients with acute heart failure (AHF) using data from a large multi-center heart failure registry. Methods and results: Data were derived from Gulf CARE (Gulf aCute heArt failuRe rEgistry), a prospective multi-center study of consecutive patients hospitalized with AHF during February–November 2012. The study included 4,157 patients, of which 306 (7.4%) were hospitalized with AHF in the fasting month of Ramadan, while 3,851 patients (92.6%) were hospitalized in other days. Clinical characteristics, precipitating factors, management, and outcome were compared among the two groups. Patients admitted during Ramadan had significantly lower prevalence of symptoms and signs of volume overload compared to patients hospitalized in other months. Atrial arrhythmias were significantly less frequent and cholesterol levels were significantly lower in Ramadan. Hospitalization in Ramadan was not independently associated with increased immediate or 1-year mortality. Conclusions: The current study represents the largest evaluation of the effects of fasting on AHF. It reports an improved volume status in fasting patients. There were also favorable effects on atrial arrhythmia and total cholesterol and no effects on immediate or long-term outcomes.

Clinical Presentation, Predictors, and Outcomes Among Mineralocorticoid Receptor Antagonist (MRA)-Eligible Acute Heart Failure Patients in the Heart Function Assessment Registry Trial in Saudi Arabia (HEARTS)

Mineralocorticoid receptor antagonist (MRA) therapy is indicated after myocardial infarction in patients with acute heart failure (AHF) with an ejection fraction ≤40% and lacking contraindications. We analyzed clinical presentations, predictors, and outcomes of MRA-eligible patients within a prospective registry of patients with AHF from 18 hospitals in Saudi Arabia, from 2009 to 2010. For this subgroup, mortality rates were followed until 2013, and the clinical characteristics, management, predictors, and outcomes were compared between MRA-treated and non-MRA-treated patients. Of 2609 patients with AHF, 387 (14.8%) were MRA eligible, of which 146 (37.7%) were prescribed MRAs. Compared with non-MRA-treated patients, those prescribed MRAs more commonly exhibited non-ST-segment elevation myocardial infarction, acute on chronic heart failure, past history of ischemic heart disease, and severe left ventricular systolic dysfunction; were more commonly administered oral furosemide and digoxin; and had higher in-hospital recurrent congestive HF rates. Mortality did not significantly differ (P > .05) between groups. In Saudi Arabia, 37.7% of eligible patients received MRA treatment, which is higher than that in developed countries. The lack of long-term survival benefit raises concerns about systematic problems, for example, proper follow-up and management after hospital discharge, warranting further investigation.

Atrial Fibrillation in Patients Hospitalized With Heart Failure: Patient Characteristics and Outcomes From the HEARTS Registry

Effect of atrial fibrillation (AF) on short- and long-term outcomes in heart failure (HF) is controversial. Accordingly, we examined this relationship in a national multicenter project using data from the Hearts Function Assessment Registry Trial in Saudi Arabia that studied the clinical features and outcomes of patients admitted with de novo and acute on chronic HF. Out of 2593 patients with HF, 449 (17.8%) had AF at presentation. Patients with AF were more likely to be males and older (mean age 65.2 ± 15.0 vs 60.5 ± 14.8 years) to have a history of ventricular tachycardia/ventricular fibrillation (3.1% vs 1.9%) or cerebrovascular accident (15.0% vs 8.5%). However, they were less likely to have diabetes (66.0% vs 55.9%) or coronary artery disease (55.6% vs 42.3%). The 1-, 2-, and 3-year crude mortality rates were significantly higher in patients with AF (23.2% vs 18.3%, 27.4% vs 22.3%, and 27.8% vs 23.2%, respectively). However, there was no significant difference in mortality after adjusting for covariates. Thus, in patients admitted with HF, AF upon presentation was not associated with increased mortality.

Circadian Rhythm and ST-Segment Elevation Myocardial Infarction: Insights From the Third Gulf Registry of Acute Coronary Events (Gulf RACE-3Ps)

Circadian rhythms have been identified in multiple physiological processes that may affect cardiovascular diseases, yet little is known about the impact of circadian rhythm on acute ST-segment elevation myocardial infarction (STEMI) onset and outcomes in the Middle East. The relationship between time of symptom onset during the 24-hour circadian cycle and prehospital delays and in-hospital death was assessed in 2909 patients with STEMI presenting in 6 Arabian Gulf countries. A sinusoidal smoothing function was used to show the average circadian trends. There was a significant association between time of symptom onset and the circadian cycle. The STEMIs were more frequent during the late morning and early afternoon hours (P < .001). Patients with pain onset from 0.00 to 5:59 had median prehospital delays of 150 minutes versus 90 minutes from 6:00 to 11:59 and 12:00 to 17:59, respectively (P < .001). Although there was no significant difference in mortality between the 4 groups (P = .230), there was a significant association between time of symptom onset as sinusoidal function and in-hospital mortality (P = .032). Patients with STEMI in the Middle East have significant circadian patterns in symptoms onset, prehospital delay, and timeliness of reperfusion. A circadian rhythm of in-hospital mortality was found over the 24-hour clock of symptom onset time.

Clinical characteristics, management and outcomes of patients with chronic heart failure: Results from the heart function assessment registry trial in Saudi Arabia (HEARTS-chronic)

BACKGROUND Several registries have described patients hospitalized with heart failure (HF), but only few looked at outpatients in the ambulatory setting mostly without long-term follow-up. We sought to determine the clinical characteristics, management, and 1-year outcomes of patients with chronic HF in Saudi Arabia. METHODS Part of a prospective multicenter nationwide registry; HEart function Assessment Registry Trial in Saudi Arabia (HEARTS) and included chronic HF patients referred to four HFCs between September 2009 and December 2011. RESULTS We enrolled 685 patients with mean age 55.66±15.97years, 70.1% were men and 96.1% were Saudis. The main etiologies of HF were CAD (38.8%), dilated cardiomyopathy (36.5%), and hypertension (10.5%). Severe left ventricular dysfunction was present in 70.6% and median NT-proBNP was 2934.37pg/ml. The prescription rates of evidence based therapies (EBTs) before admission to HFC, at discharge from 1st clinic visit, and at 1-year follow up were 90%, 91% and 94% for beta-blockers, 79%, 80%, and 86% for ACEi/ARBs and 44%, 45%, and 42% for aldosterone antagonists; respectively. ICD was inserted in 21.9% and CRT in 6.6% at enrollment and increased to 29.1% and 8.8% after one year respectively. The all-cause mortality rate at 1year was 9% and 93.7% of which was cardiac-related. The all-cause one-year hospitalization rate was 39% and the total emergency room visit rate was 50%. CONCLUSIONS Chronic HF patients in Saudi Arabia are younger, commonly have severe LV systolic dysfunction and have relatively high annual mortality and re-hospitalization rates.

Bentall Procedure for an Adult Patient with Supravalvular Aortic Stenosis and Coronary Aneurysms

We describe the surgical management of a 35‐year‐old male with multiple coronary aneurysms and a diffuse form of supravalvular aortic stenosis who presented with acute myocardial infarction and left ventricular dysfunction. The patient underwent a Bentall procedure with left internal mammary artery to left anterior descending artery bypass grafting with the use of cardiopulmonary bypass utilizing the right axillary artery for arterial cannulation. doi: 10.1111/jocs.12119 (J Card Surg 2013;28:394–396)
