顧小培丨食薄血藥易誘發胃痛? 健康食品可代替薄血藥?

薄血藥一般是’通波仔’ 手術後所需要服用的藥物。近年通波仔手術普及化,大部份患有心血管疾病的患者,普遍選擇做’通波仔’手術,由於進行手術後,血管於短時間內仍有再次堵塞的風險,醫生一般會處方薄血藥來減低堵塞風險。但免疫學博士顧小培指出,薄血藥會誘發胃痛。到底原因是甚麼呢?

為何通波仔後要服用薄血藥?

通波仔手術後,醫生一般會留下1、2條支架,將血管撐開,防止再次堵塞。顧博士補充,現時新式的支架會慢慢溶化,但舊式支架會永久留於血管內。


血液於血管內,穿過支架時由濶,經過窄的血管,做成’封洞效應’ (wind tunneling),封洞效應會令血液流得較快,而血液流得快的現象稱為’邊緣效應’。


邊緣效應會將血液中的血小板,向血管2邊推開,令血小板容易黐在一起,再次堵塞血管。有見及此,醫生便處方薄血藥,防止血小板黐成一團。
