Chapter 49: Cardiovascular Disorders (Adult Clients)

The chapter then systematically addresses major disease processes: coronary artery disease and acute coronary syndromes present with characteristic anginal presentations and myocardial tissue injury; heart failure involves systolic and diastolic dysfunction with distinct hemodynamic consequences; inflammatory conditions such as pericarditis, myocarditis, and endocarditis result from infectious or autoimmune processes affecting cardiac layers; and vascular disorders including hypertension, aneurysmal disease, and thromboembolism represent structural or functional aberrations in blood vessel integrity and function. Diagnostic modalities are extensively covered, spanning electrocardiographic interpretation for rhythm identification and ischemic changes, echocardiography for structural and functional assessment, cardiac biomarkers and natriuretic peptides for necrosis and ventricular strain detection, and invasive procedures such as cardiac catheterization for definitive coronary anatomy visualization. Pharmacological management encompasses multiple drug classes including nitrates, beta-adrenergic blockers, calcium channel antagonists, angiotensin-converting enzyme inhibitors, and anticoagulant agents, each with specific mechanisms and clinical indications. Interventional and surgical therapies including percutaneous coronary angioplasty, coronary artery bypass grafting, valve repair or replacement, and implantable devices address structural and hemodynamic complications. The chapter emphasizes nursing priorities throughout acute and chronic disease states, including hemodynamic monitoring, pain management, fluid balance optimization, dysrhythmia recognition and response, cardiopulmonary resuscitation protocols, and patient education regarding medication adherence, lifestyle modification, and symptom recognition. Preventive strategies and risk factor modification form an integral component of comprehensive cardiovascular care.
