Place bacon in a large, deep frypan. Cook over medium high heat until evenly brown. Drain, crumble and set aside.
Meanwhile, bring a large saucepan of lightly salted water to a boil. Add asparagus and cook until tender; about 1 minute. Strain asparagus out of water and immediately plunge into a bowl filled with ice water; let sit in ice water until completely cold then cut into 2cm pieces.
Add pasta to boiling water and cook for 8 to 10 minutes or until al dente. Drain, rinse with cold water until chilled then drain well.
Stir together mayonnaise, balsamic vinaigrette, lemon juice and Worcestershire sauce in a large bowl. Fold in artichoke, chicken, cranberries, almonds, crumbled bacon and asparagus. Season to taste with salt and pepper then fold in cooked pasta. Refrigerate for at least 1 hour before serving.
