Recognizing Symptoms of an Arterial Embolism
The symptoms of an arterial embolism can manifest gradually or suddenly, depending on the size of the embolus. Furthermore, the specific artery that the embolus obstructs affects the symptoms experienced. Common signs include localized pain in the affected area and temporary impairment of organ function. Over time, the embolism can lead to tissue death, known as infarction, resulting from inadequate oxygenated blood supply. Infarctions have long-term consequences on the affected area’s functionality and can also give rise to additional complications. For instance, a myocardial infarction in the heart may cause chest pain, dizziness, and nausea.
Causes of Arterial Embolism
Arterial embolisms can occur due to various risk factors. Any injury to the arterial wall can increase the likelihood of developing an arterial embolism. Additionally, conditions or procedures that disrupt normal blood flow pose a significant danger. One of the primary causes of arterial embolisms is atherosclerosis, a disease characterized by the build-up of plaque along the inner walls of arteries, leading to severe narrowing. Consequently, atherosclerosis and arterial embolisms often share common risk factors. Factors such as cigarette smoking, hypertension, obesity, stress, diabetes, and a sedentary lifestyle all contribute to an increased risk of developing both atherosclerosis and arterial embolism.
