The 1958 US measure was an arms embargo against the Batista government (arms shipments suspended in mid-March 1958), not an economic blockade against Cuba's island and population.
The economic/trade blockade began in 1960: Eisenhower imposed the first economic sanctions against Cuba's revolutionary government in 1960, and the State Department's trade embargo was imposed on 19 October 1960.
The blockade was formalised and extended by Proclamation 3447 on 7 February 1962, which prohibited all trade with Cuba.
The claim's framing conflates an early arms embargo (1958) with the later comprehensive economic blockade, artificially lengthening the timeline by about two years.
