The harmful effects of cigarette smoking on the human body have been well documented. However, whether tobacco use is an independent risk factor of valvular heart disease remains debatable. Cigarette smoking has been associated with an inflammatory state and increased levels of tumor necrosis factor alpha, which in turn activates protein kinases involved in ventricular remodeling. Subsequent ventricular dysfunction predisposes to the formation of mural thrombi which may lead to further worsening of hemodynamics. We present a case of severe aortic stenosis and giant left ventricular thrombus formation associated with chronic cigarette smoking.
吸烟对人体的有害影响已有充分记载。然而,烟草使用是否为心脏瓣膜病的独立危险因素仍存在争议。吸烟与炎症状态及肿瘤坏死因子α水平升高有关,进而激活参与心室重塑的蛋白激酶。随后的心室功能障碍易引发壁血栓形成,这可能导致血流动力学进一步恶化。我们报告一例与慢性吸烟相关的严重主动脉瓣狭窄及巨大左心室血栓形成的病例。
