Out of all the EET positive patients, 29 (27.6%) patients had single vessel disease
, 31 (29.5%) double vessel disease and 60 (57.1%) patients had triple vessel disease on angiography as shown in figure.
Patients were classified as single vessel disease
if only one vessel had significant stenosis, double vessel disease if two vessels were involved and triple vessel disease if 3 vessels were involved.
The distributions of diseased vessels in the CS group compared with the non-CS group were single vessel disease
, 34.0% versus 39.2%; dual vessel disease, 30.2% versus 35.2%; and triple vessel disease, 35.8% versus 25.6% (P = 0.285).
A majority of the patients (80, 74.77%) had single vessel disease
. Normal coronaries arteries was found in 9 (8.41%) patients.
The recovery time (ST depression to baseline) was less than 3 minutes in seven subjects with non-occlusive atheroma (FP) and in 9 patients with single vessel disease
. One patient with severe SVD (95% stenosis proximal LAD) had a prolonged recovery time of greater than 9 minutes.
Genotype frequencies of B2B2, B2B1 and B1B1 were respectively: 29%, 45% and 26% in controls, 18.1%, 50% and 31.9% in single vessel disease
, 18.7%, 33.3% and 48% in double vessel disease and 27%, 31.7% and 41.3% in triple vessel disease.
(10,11) In term of angiographic findings, younger patients tend to have more normal coronary arteries and single vessel disease
compared to older patient who tend to have more complex and multiple vessels involvement.
CAD patients consisted of 17 subjects with single vessel disease
, 20 subjects with double vessel disease, and 23 subjects with triple vessel disease.
Patients with multivesel disease, complex disease, CTO and single vessel disease
are preferred for PCI.
Although the mean age was 48 yr, TVD was more common (55%) than DVD (24%) and single vessel disease
Percutaneous transcatheter stent implantation is preferred in patients with a single vessel disease
, which is not involving the LMCA, especially in localized and not extended dissections (9).
Young age group in our study had higher frequency of single vessel disease
(64.15%) when compared with their older counterparts (29%).
