The 120 patients with CHD were categorized into single-vessel disease
group, double-vessel disease group, and three-vessel disease group based on the number of coronary artery stenosis.
Patients with single-vessel disease
had only occlusion in IRA.
In the present study, we compared the risk factors and short-term outcome between young ACS patients with single-vessel disease
(SVD) or MVD.
Regarding the severity of IHD, 21.8% had single-vessel disease
(SVD),60.3% had double - vessel disease (DVD) while 17.9% had three-vessel disease (TVD).
 showed single-vessel disease
was greater than others (44%).
Using coronary angiography, the study population was divided into subjects without any angiographically detectable CAD or with coronary arterial stenoses less than 50% (no vessel disease; n=ioo) and individuals with single-vessel disease
(n=72), double-vessel disease (n=75) or triple-vessel disease (n=63) (Table 1).
Patients were assigned according to the number of coronary arteries affected by significant stenosis as having single-vessel disease
, two-vessel disease, or multi-vessel disease.
C0: Normal coronary artery, C1: Non-critical plaque, C2: Single-vessel disease
, C3: Double-vessel disease, C4: Multiple-vessel disease, C5: Left main coronary disease; P0: Normal peripheral arteries, P1: Non-critical plaques, P2: Proximal critical single stenosis, P3: Distal stenoses, P4: Stenoses or complete occlusion in all segments.
The Octopus population comprised 280 low-risk patients with preserved left ventricular function, single-vessel disease
, and a mean age of 60 years.
It randomized patients with diabetes and either multivessel coronary disease or complex single-vessel disease
who were suitable for either PCI or coronary artery bypass grafting (CABG).
Results Arteriography revealed that 14% of patients had normal coronary arteries, 35% had single-vessel disease
, 34% had 2-vessel disease, and 17% had 3-vessel disease.
Using coronary angiography, 15 (22%) AMI patients had single-vessel disease
, 29 (42%) had double-vessel disease, and 25 (36%) had triple-vessel disease.
