概括
在2型糖尿病 (T2DM) 中将血压降低到120/70mmHg左右,可以轻微减少心血管事件和微血管并发症,如视网膜病变和白膜尿. 然而,神经病变的风险需要进一步调查.
科学领域:
- 心脏病学 心脏病学
- 内分泌学 在内分泌学.
- 腎臟病學 (nephrology) 是一種醫學專業.
背景情况:
- 对2型糖尿病 (T2DM) 的最佳血压 (BP) 目标仍有争议,特别是在最近的大型试验之后.
- 密集降低血压的心血管益处和危害之间的权衡需要持续评估.
研究的目的:
- 在T2DM中更新有关密集与标准血压控制的证据.
- 通过包括BPROAD试验数据,重新评估心血管和微血管结果.
主要方法:
- 8个随机对照试验 (25,686名参与者) 的元分析.
- 强烈的BP目标:~120/70 mmHg;标准的BP目标:~135/80 mmHg.
- 主要终点:复合心血管事件;次要终点:视网膜病变,神经病变,尿液中的白蛋白分泌 (UAE).
主要成果:
- 强烈的血压降低减少了心血管事件 (OR 0.88,95% CI 0.79-0.97).
- 在视网膜病变 (OR 0.84,95% CI 0.71-0.98) 和阿联 (OR 0.82,95% CI 0.71-0.94) 中观察到显著改善.
- 神经病变风险增加 (OR 1.48,95% CI 1.05-2.10),尽管由于样本规模小,信心有限.
结论:
- 在T2DM中,120/70 mmHg的BP目标与适度的心血管和微血管益处有关.

Diabetes: Management and Pharmacotherapy
851
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.

Diabetes Mellitus: Type 2 and Gestational
4.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Diabetes Mellitus: Overview and Type I Subtype
4.8K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Carbohydrate Metabolism
13.7K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

Hypertension III: Clinical Manifestations and Diagnostic Studies
451
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension IV: Drug Therapy and Lifestyle Modifications
595
Multiple classes of antihypertensive medications are employed in treating hypertension. The most commonly recommended first-line treatments include:Thiazide Diuretics, such as chlorthalidone, increase sodium and water excretion from the body, reducing blood volume and blood pressure.Angiotensin-converting enzyme inhibitors, like lisinopril, block the conversion of angiotensin I to II, a potent vasoconstrictor lowering blood pressure.Angiotensin II Receptor Blockers (ARBs) prevent angiotensin II...
