aspirin is not just about platelets/coagulation.
It also addresses endothelial dysfunction in oxidative stress and increases nitric oxide availability.

Aspirin preserves the integrity of the vascular wall through its free radical scavenging properties and its capacity to protect endothelial cells from the deleterious effects of hydrogen peroxide (16, 21, 40). The effects of aspirin in preventing cardiovascular events are attributed to its platelet-inhibitory function, which results from the irreversible inhibition of the activity of platelet cyclooxygenase and thromboxane B2, the major products of cyclooxygenase (COX-1) activity (39). Low-dose aspirin suppresses the age-related increase in oxidative stress via the modulation of NF-B (27). The acetyl group provides aspirin with the capacity to increase endothelial nitric oxide (NO) synthesis and bioavailability (14, 15, 24, 46, 53). Aspirin reduces monocyte chemoattractant protein-1 and soluble ICAM-1 levels in low-density lipoprotein (LDL) receptor-deficient mice (8, 9). This reduction in adherence molecule expression has a functional effect, since aspirin inhibits monocyte adhesion to LDL-stimulated endothelial cells (15). Evidence from explorative clinical trials suggests that treatment with low-dose aspirin increases EDR. In humans, low-dose aspirin administered over a 2-mo period has been found to improve endothelial function (34). In rats with vascular endothelial injury induced by an injection of native LDL, low-dose aspirin is able to reverse the EDR dysfunction (11).

Aspirin and the entire endothelial health program were not enough for Jeff to overcome his fatigue. He had such severe stenosis, he would fall asleep driving and had to stop after a fender bender.
Since angioplasty, he is awake full days, no naps, and back to working and driving. For some, aspirin can only do so much.
