No Cenário Atual, Qual O Papel Dos Betabloqueadores No Tratamento Da Hipertensão?

Abstract: As teorias sobre a existência de receptores adrenérgicos foram descritas na literatura em meados da década de 40, sendo reconhecido anos depois que a inibição do sistema nervoso simpático por um determinado composto bloqueador beta adrenérgico poderia beneficiar pacientes com arritmias cardíacas e angina pectoris. Nasceram aí as primeiras substâncias bloqueadoras beta adrenérgicas não seletivas, destacando-se o propranolol. Desde então, centenas de bloqueadores betaadrenérgicos (BB) foram sintetizados e dezena… Show more

When we compared this variable, we observed that in group 1 the hemorrhage scores are slightly lower than in group 2.…”
