People with type II diabetes have a twofold to fourfold increased risk of dying from the complications of cardiovascular disease. Atherosclerosis and vascular thrombosis are major contributors. The increased risk is present before fasting hyperglycemia is seen. These individuals often have a sedentary life-style, poor physical conditioning, insulin resistance, centripetal obesity, hypertension, dyslipidemia, and a prothrombotic state. Chronic hyperglycemia is then added to these risk markers. Microalbuminuria may precede hyperglycemia in type II diabetes, occurs in 30% to 40% of these individuals after diabetes is established, and is a predictor of cardiovascular events. Early intervention in high-risk individuals may delay or prevent fasting hyperglycemia. An all-inclusive approach that focuses on early risk factor (or marker) identification and management to prevent or delay accelerated atherosclerosis and thrombosis in type II diabetes is an attractive strategy. However, the database to support this strategy is limited. In particular, large-scale prospective trial data are not available to support the concept of intensive glycemic regulation to prevent progression of macrovascular disease in type II diabetes. This is in contrast to the situation regarding microvascular disease of the eyes and kidneys. Recently, indirect data of a correlative nature have emerged, and short- and long-term prospective trials at early and late stages of type II diabetes are now being reported. These studies are analyzed and interpreted in this report. In contrast, the database to support an intensive antiplatelet regimen to prevent vascular thrombotic events in people with type II diabetes is large, and these studies are reviewed. They are of a type and magnitude to allow definite recommendations for aspirin therapy in type II diabetes. Aggressive therapy directed at hypertension, hyperlipidemia, and elevated urinary albumin in people with type II diabetes appears to be indicated. Increased attention to the multifactorial aspects of treatment of the type II diabetic patient is needed. Our present challenge is to translate these findings for patients and primary health care providers so that effective actions may be implemented.
2型糖尿病患者死于心血管疾病并发症的风险增加了2至4倍。动脉粥样硬化和血管血栓形成是主要原因。在出现空腹血糖升高之前,风险就已增加。这些个体通常生活方式久坐、身体状况不佳、存在胰岛素抵抗、向心性肥胖、高血压、血脂异常以及血栓前状态。随后慢性高血糖又叠加在这些风险指标之上。微量白蛋白尿在2型糖尿病中可能先于高血糖出现,在糖尿病确诊后,30%至40%的患者会出现微量白蛋白尿,它是心血管事件的一个预测指标。对高危个体进行早期干预可能会延缓或预防空腹血糖升高。一种全面的方法,即专注于早期风险因素(或标志物)的识别和管理,以预防或延缓2型糖尿病中动脉粥样硬化和血栓形成的加速发展,是一种有吸引力的策略。然而,支持这一策略的数据库有限。特别是,没有大规模前瞻性试验数据来支持强化血糖调节以预防2型糖尿病大血管疾病进展的概念。这与眼睛和肾脏微血管疾病的情况形成对比。最近,出现了一些相关性的间接数据,目前也有关于2型糖尿病早期和晚期的短期和长期前瞻性试验报告。本报告对这些研究进行了分析和解读。相比之下,支持强化抗血小板治疗方案以预防2型糖尿病患者血管血栓形成事件的数据库很大,并且对这些研究进行了综述。这些研究的类型和规模足以对2型糖尿病患者的阿司匹林治疗给出明确建议。对2型糖尿病患者的高血压、高脂血症和尿白蛋白升高进行积极治疗似乎是必要的。需要更加关注2型糖尿病患者治疗的多因素方面。我们目前面临的挑战是将这些发现转化为患者和初级医疗保健提供者能够理解的内容,以便能够采取有效的行动。
