Our hearts hold our lives. Even when we handle our heart with utmost caution, surgery for problems unrelated to the heart can damage heart cells. This could be sometimes deadly too in the case of few patients, according to a new study. The risk of dying was greater in patients who were 65 years or older, or had pre-existing heart problem.
Such type of heart damage that can develop during or after surgery is called as perioperative myocardial injury (PMI). Individuals with PMI are rarely diagnosed for the same as there are no symptoms indicative of the diseases in most cases and rarely someone might experience chest pain (relative symptom of heart attack).
The study included 2,000 women and men who had heart disease or were at an increased risk of developing heart disease. Among these individuals, some patients had undergone knee surgery which had low risk of death, some patients were operated for moderate risk procedures such as hip replacement or gall bladder removal and few other patients underwent complicated procedures, such as surgery to remove part of the lung or the liver. Different diseases, their causes and treatment procedures are elaborated at www.firsteatright.com from which you can completely understand the history behind them.
Researchers linked the surgery these individuals underwent with heart damage by measuring the patient’s level of troponin (heart protein found in blood) before and after the surgery. Using this protein measure enabled the researchers to identify patients who developed PMI, regardless of whether they displayed any of the associated symptoms.
The study also found that one out of seven patients who were 65 years or older diagnosed with coronary heart disease, peripheral heart disease or stroke developed PMI. These patients were six times likelier to die of some reason in the next 30 days following their surgery than those who did not succumb to PMI. The increased death rate associated with PMI continued up to a year after surgery.
Understanding that PMI might be a grave outcome of surgeries helps to improve the outcomes of non-heart surgeries. There is no specific treatment for these patients and treatment has to be personalized for the patients individually.
