The risk for cardiovascular disease (CVD) is multifactorial and includes such risk factors as diabetes, hypertension, smoking, and dyslipidemia. Thus, targeting the hyperglycemia in type 2 diabetes mellitus (DM) alone will not eliminate all of the excess cardiovascular risk; rather aggressive treatment is needed for all of the modifiable cardiometabolic risk factors. Therapeutic lifestyle change is considered primary therapy for hyperglycemia in type 2 DM. Currently, however, the focus in treatment is on preventing CVD rather than controlling glucose, lipid, or blood pressure (BP) levels. The American Diabetes Association guidelines identify low-density lipoprotein cholesterol as the first priority of lipid lowering, with optimal level set at <100 mg/dL (2.6 mmol/L). To reach the target BP level of <130/85 mm Hg, >65% of patients with DM and hypertension will require 2 or more different antihypertensive drugs. Strategies that combine thiazolidinediones and statins may have complementary effects on cardiovascular risk-factor profiles in type 2 DM, in addition to controlling glycemia. Despite the range of treatment options available, therapeutic agents that target new steps in the progression of CVD are needed, as patients with type 2 DM remain at increased risk and many do not achieve therapeutic targets with the drugs available.
心血管疾病(CVD)的风险是多因素的,包括糖尿病、高血压、吸烟和血脂异常等风险因素。因此,仅针对2型糖尿病(DM)中的高血糖并不能消除所有额外的心血管风险;相反,需要对所有可改变的心脏代谢风险因素进行积极治疗。治疗性生活方式改变被认为是2型DM高血糖的主要治疗方法。然而,目前治疗的重点是预防CVD,而不是控制血糖、血脂或血压(BP)水平。美国糖尿病协会指南将低密度脂蛋白胆固醇确定为降脂的首要目标,最佳水平设定为<100 mg/dL(2.6 mmol/L)。为了达到<130/85 mmHg的目标血压水平,超过65%的DM合并高血压患者需要2种或更多不同的抗高血压药物。除了控制血糖外,噻唑烷二酮类药物和他汀类药物联合使用的策略可能对2型DM患者的心血管风险因素状况具有互补作用。尽管有多种治疗选择,但仍需要针对CVD进展新步骤的治疗药物,因为2型DM患者的风险仍然较高,而且许多患者使用现有药物无法达到治疗目标。
