Cardiovascular disease (CVD) presents an enormous and growing burden on the Canadian health care system. Elevated serum low-density lipoprotein cholesterol levels are an established, major risk factor in the development of premature CVD. There is strong evidence that 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, or statins, significantly lower both low-density lipoprotein cholesterol levels and CVD risk. However, there is currently a treatment gap, in that a large segment of the population who should be receiving statins due to elevated serum cholesterol levels are not. Individuals at moderate risk of developing CVD represent one large population segment that is currently being undertreated. This group may be a candidate for receiving over-the-counter (OTC) or behind-the-counter (BTC) statins, which may be a suitable primary prevention strategy. Nonetheless, it must be noted that hypercholesterolemia is a complex, chronic condition that must be carefully managed and requires close consultation with a health care practitioner. The advantages and disadvantages of OTC or BTC statin usage must therefore be carefully weighed before any potential introduction of OTC or BTC statins in Canada.
心血管疾病(CVD)给加拿大医疗保健系统带来了巨大且不断增加的负担。血清低密度脂蛋白胆固醇水平升高是早发性心血管疾病发展过程中已确定的主要危险因素。有充分证据表明,3-羟基-3-甲基戊二酰辅酶A还原酶抑制剂(即他汀类药物)可显著降低低密度脂蛋白胆固醇水平并降低心血管疾病风险。然而,目前存在治疗缺口,即很大一部分因血清胆固醇水平升高而应服用他汀类药物的人群并未服用。具有中度心血管疾病发病风险的个体是目前治疗不足的一大群体。这一群体可能适合使用非处方(OTC)或柜台后(BTC)他汀类药物,这可能是一种合适的一级预防策略。尽管如此,必须指出的是,高胆固醇血症是一种复杂的慢性病,必须谨慎管理,需要与医疗保健从业者密切协商。因此,在加拿大任何可能引入非处方或柜台后他汀类药物之前,必须仔细权衡使用此类药物的利弊。
