Myocardial infarction
๐งฟ A myocardial infarction (MI) occurs when a thrombus blocks blood flow through a coronary artery, depriving the heart muscle of oxygen.
๐งฟ Prolonged interruption of blood flow causes ischemia followed by necrosis of the myocardium.
๐งฟ Clients may experience chest pain, shortness of breath, diaphoresis, nausea, and electrocardiographic changes.
๐งฟ Untreated myocardial infarction can lead to cardiogenic shock, life-threatening dysrhythmias, heart failure, and sudden cardiac death.
๐งฟ Rapid restoration of coronary blood flow through percutaneous coronary intervention (PCI) or thrombolytic therapy, when appropriate, improves survival.
๐งฟ Nurses should recognize symptoms promptly and activate emergency treatment protocols without delay.
๐งฟ Early intervention minimizes permanent myocardial damage and improves long-term cardiac function.
๐งฟ Myocardial infarction is a life-threatening thromboembolic emergency requiring immediate treatment.
โ
Ischemic stroke
๐งฟ An ischemic stroke occurs when a thrombus or embolus obstructs blood flow to part of the brain.
๐งฟ Brain tissue deprived of oxygen begins to die within minutes, making this a true medical emergency.
๐งฟ Common manifestations include facial drooping, arm weakness, speech difficulty, vision changes, and altered consciousness.
๐งฟ Prompt recognition using the FAST assessment allows rapid treatment and improves neurological outcomes.
๐งฟ Eligible clients may receive thrombolytic therapy or undergo mechanical thrombectomy to restore cerebral blood flow.
๐งฟ Delayed treatment increases the risk of permanent neurological deficits or death.
๐งฟ Rapid intervention preserves brain tissue and maximizes recovery potential.
๐งฟ Ischemic stroke is a life-threatening condition caused by blocked cerebral blood flow.
โ
Pulmonary embolism
๐งฟ A pulmonary embolism (PE) occurs when a blood clot, often originating from a deep vein thrombosis, travels to the pulmonary arteries.
๐งฟ The clot obstructs pulmonary circulation, reducing oxygen exchange and increasing strain on the right ventricle.
๐งฟ Manifestations include sudden dyspnea, pleuritic chest pain, tachycardia, hypoxemia, and sometimes hemoptysis.
๐งฟ A large pulmonary embolism can rapidly cause obstructive shock, cardiac arrest, and death if not treated promptly.
๐งฟ Immediate treatment may include oxygen therapy, anticoagulation, thrombolytic therapy, or embolectomy, depending on severity.
๐งฟ Early diagnosis and intervention significantly reduce mortality.
๐งฟ Nurses should recognize pulmonary embolism as one of the most serious complications of venous thromboembolism.
๐งฟ Pulmonary embolism is a life-threatening complication requiring immediate emergency management.
