Coronary artery disease due to atherosclerosis is by far the most common cause of unstable angina.
Atherosclerosis is the buildup of fatty material called plaque along the walls of the arteries. This causes arteries to become narrowed and less flexible.
The narrowing interrupts blood flow to the heart, causing chest pain.
Some of the risk factors are :
Diabetes, smoking, High LDL cholesterol Low HDL cholesterol. Male gender. Not getting enough exercise. Obesity and older age.
Chest pain associated with UA is new onset, occurs at rest, or has a worsening pattern.
Discomfort, weakness, nausea, vomiting, diaphoresis, SOB, fatigue and hypotension. Patient with chronic stable angina may develop UA or been the first manifestation of CAD. Unlike chronic stable angina UA is unpredictable and represents an emergency. Nitroglycerin, morphine and O2.
Blood thinners (antiplatelet drugs
heparin (or another blood thinner Nursing interventions in the initial included pain assessment and relieve, physiological monitoring promotion of rest and comfort, alleviation of stress and anxiety and understanding the patients emotional and behavioral reactions.
Maintain continuous ECG monitoring while the patient is in ED or ICU.
Frequent V/S assesses, check intake and output at least once per shift.
Assess lungs and heart sounds and inspect for evidence of early heart failure, e.g. tachycardia, dyspnea. pulmonary congestion,
Assess patient saturation status, especially if the patient is receiving Oxygen Treatment.
