Abstract Purpose The combination of obesity and diabetes mellitus are well-known risk factors for cardiovascular complications and perioperative morbidity in metabolic surgery. The aim of this study was to evaluate effectivity and reliability of the cardiac assessment in patients with diabetes prior to bariatric surgery. Setting Private, university-affiliated teaching hospital, Switzerland Material and Methods Retrospective analysis of prospectively collected data on results and consequences of cardiac assessments in 258 patients with obesity and diabetes scheduled for primary bariatric surgery at our institution between January 2010 and December 2018. Results Out of 258 patients, 246 (95.3%) received cardiac diagnostics: 173 (67.1%) underwent stress-rest myocardial perfusion scintigraphy (MPS), 15 (5.8%) patients had other cardiac imaging including cardiac catheterization, 58 (22.5%) patients had echocardiography and/or stress electrocardiography, and 12 (4.7%) patients received no cardiac evaluation. Subsequently, cardiac catheterization was performed in 28 patients (10.9%), and coronary heart disease was detected and treated in 15 subjects (5.8%). Of these 15 individuals, 5 (33.3%) patients had diffuse vascular sclerosis, 8 (53.3%) patients underwent coronary angioplasty and stenting, and 2 (13.3%) patients coronary artery bypass surgery. Bariatric surgery was performed without perioperative cardiovascular events in all 258 patients. Conclusion Our data suggest that a detailed cardiac assessment is mandatory in bariatric patients with diabetes to identify those with yet unknown cardiovascular disease before performing bariatric surgery. We recommend carrying out myocardial perfusion scintigraphy as a reliable diagnostic tool in this vulnerable population. If not viable, stress echocardiography should be performed as a minimum.

Four infants, aged 16 to 28 days (mean 23 days), were seen in the emergency room with acute cardiovascular collapse and with normal heart rate and rhythm. During evaluation for cardiovascular collapse, no infant had sepsis; cardiac assessment revealed normal intracardiac anatomy but global cardiac chamber enlargement and poor left ventricular systolic function, which resolved with supportive treatment. However, three of the four infants demonstrated ventricular preexcitation on their surface electrocardiogram and, subsequently, two infants had transient episodes of tachycardia. During a transesophageal pacing study to evaluate inducibility and electrophysiologic characteristics of tachycardia, sustained tachycardia was initiated in all four infants. Reentrant tachycardia used an accessory atrioventricular connection as evidenced by (1) the presence of preexcitation during sinus rhythm (three infants), (2) the ability to initiate and terminate tachycardia by programmed electrical stimulation (four infants), (3) minimum ventriculoatrial interval recorded in the esophagus (V-Aeso) exceeded 70 ms (four infants), (4) transient bundle branch block during tachycardia prolonged the cycle length and the V-Aaso by 30 to 50 ms (three infants). Findings in these infants suggested prior episodes of prolonged tachycardia as the probable etiology of the cardiovascular collapse.

Cardiovascular disease remains a major cause of death in the United Kingdom. The early recognition of cardiovascular deterioration in the acutely ill patient is an essential skill for practitioners in acute care. This chapter offers an overview of the cardiovascular system and normal physiological and compensatory mechanisms which support cardiovascular function. Cardiac assessment is explored in some detail including symptom review, cardiac monitoring, and chest pain assessment. The complex subject of arrhythmia interpretation and management is reviewed in some depth. The chapter concludes with a focus on the management of acute coronary syndromes, heart failure, and cardiogenic shock. All three conditions are potentially life-threatening and rapid assessment and treatment is essential to prevent mortality; evidence-based management of these conditions is considered in detail within this chapter.

It is essential that the cardiac nurse can carry out a comprehensive cardiac assessment of their patient. The nursing assessment aims to describe the patient’s condition and help determine an accurate diagnosis, so that an effective and timely clinical management plan is implemented. The focus of the initial assessment varies according to the setting and clinical presentation of the patient. However, the priority is always to determine whether the patient is haemodynamically stable, whether they are suffering from an acute cardiac event that would benefit from time-dependent therapy, and the need for symptom management. A thorough cardiac assessment requires the nurse to use a wide range of interpersonal, observational, and technical skills. Additionally, the nurse needs an in-depth knowledge of cardiac anatomy, physiology, and pathophysiology to determine the significance of the findings. This chapter outlines how to assess key symptoms and signs of cardiac disease. Symptoms are things that the patient reports as troublesome issues; signs are associated physiological changes that the health professional might discover during the course of their assessment.
