var card_info_array = document.getElementsByClassName('progress_info_bold'); 
var result = 0; 
for (var iterator = 0; iterator < card_info_array.length; iterator++) { 
  var current_result_array = card_info_array[iterator].innerHTML.split(' ');
  for (var item = 0; item < current_result_array.length; item++) {
    if (!isNaN(parseInt(current_result_array[item]))) {
      result+= +current_result_array[item];
      break;
    }
  } 
}
console.log(result);

jQuery variant:

var result = 0;
jQuery('.progress_info_bold').each(function(key, val) {
    result+= parseInt(jQuery(val).html().match(/\d+$/), 10);
});
console.log(result);
