The oxygen consumption of the heart accounts for about 20% of the oxygen consumption of the human body. If the lungs are diseased, the heart will be the first to suffer from hypoxia. Long-term hypoxia will lead to an increase in heart rate and heart load, which will eventually lead to heart disease.
心脏耗氧量约占人体耗氧量的20%,如果肺部出现病变,首先出现缺氧的就是心脏。长期缺氧会导致心率加快、心脏负荷增加,最终引起心脏病的发生。
