BACKGROUND: Compliance with self-care and lifestyle modification is recommended for all patients with acute coronary syndrome to prevent a secondary attack. Data is limited regarding the association between compliance with self-care and restenosis. This study was conducted to examine the association between compliance with self-care and restenosis and to determine the predicting factors for restenosis and low compliance with self-care. METHODS: A total of 166 acute coronary syndrome patients (64.2+/-10.8 years) hospitalized for an angiogram during routine follow-up or symptom management were conveniently recruited from a university hospital cardiovascular care unit. Self-administered questionnaires were used to evaluate the level of compliance with self-care and symptom-related satisfaction. RESULTS: In-stent restenosis was found in 40.4% of the subjects and 36.1% were persistently smoking. There was no significant relationship between low compliance with self-care and restensosis. A lower symptom-related satisfaction significantly predicted restenosis and low compliance with self-care. A longer period after initial diagnosis predicted restenosis and a shorter period after initial diagnosis predicted low compliance with self-care. Persistent smoking was independently associated with low compliance with self-care. CONCLUSIONS: Patients who continued to smoke and had lower symptom-related satisfaction with daily living showed a stronger tendency for lower compliance with self-care and lifestyle modification. Effective educational strategy focusing on smoking cessation is needed to increase compliance with self-care in patients with ACS, especially during admission with a first heart attack.

The pulmonary arterial pressure(PAP) was reported to be higher in essential hypertensives than in normotensives, but the underlying mechanisms for the higher PAP were not known exactly. In order to observe the changes of pulmonary hemodynamics and to get an insight into the mechanism of the pulmonary hypertension, if any, in essential hypertensive patients, the autors performed the cardiac catheterization in 13 normal controls(group A), 14 coronary patients with normal systolic left ventricular function and systemic blood pressure(group B), and 15 essential hypertensives with normal coronary artery and systolic left ventricular function(group C). 1)Pulmonary arterial pressure(PAP) was 19.2+/-3.2/8.1+/-1.9/12.0+/-1.9(s/d/m)mmHg in group A, 25.0+/-6.2/12.8+/-4.0/16.3+/-4.5mmHg in group B, 29.3+/-6.1/12.8+/-4.0/18.2+/-3.6mmHg in group C. The PAP was higher in group B and C than that of group A(p<0.005). 2) Pulmonary vascular resistance(PVR) was 88.2+/-34.9 dyne.sec.cm(-5) in group A. 137.8+/-74.5 dyne.sec.cm(-5) in group B and 173.9+/-77.5 dyne.sec.cm(-5) in group C. In group B and C, PVR was increased compared to that of group A(p<0.05, p<0.005, respectively). 3) Pulmonary capillary wedge pressure(PCWP) was 6.6+/-2.8 mmHg in groupa A. 9.9+/-2.9mmHg, and 9.6+/-3.6 mmHg in group C. PCWP in group B and C were higher than that of group A(p<0.005). 4) Systemic vascular resistance(SVR) was 1298+/-340 dyne.sec.cm(-5) in group A, 1466+/-362 dyne .sec.cm(-5) i group B and 2255+/-439 dyne.sec.cm(-5) in group C. In group C, SVR was increased compared to that of group A and B(p<0.002). 5) Significant correlation was demonstrated between PVR and PCWP in group A(r=-0.74, p<0.05). 6) In group B, significant correlations were shown between PAP and PCWp(r=0.55, p<0.05), between PAP and PVR(r=0.69, p<0.05). 7) In group C, significant correlations were demonstrated between PAP and PCWP(r=0.55, p<0.05), between PVR and SVR(r=<0.51, p<0.01). Above results revealed that PAP and PVR were increased in essential hypertensives without left ventricular failure and this elevated PAPseemed to be affected in part by increased PCWP, and increased PVR in accordance with increased SVR.

Hypertensive left ventricular hypertrophy(LVH) was considered to be a physiologic adaptation to the increased afterload of left ventricle, but recent studies revealed that LVH was one of the most important target organ damage in essential hypertensive patients & cardiovascular morbidity was increased in patients with hypertensive LVH. Hypertensive LVH could be classified into three types : concentric LVH, disproportionate septal thickening(DST), and left ventricular dilatation. Relatively high incidence of DST in hypertension has bee reported after clinical introduction of echocardiogram. But, the mechanisms for the development of DST and its clinical significance have not been elucidated exactly. In order to assess left ventricular diastolic function in hypertensives with DST, the authors performed phonocardiogram, M-mode, and pulsed Doppler echocardiogram in 15 normotensive control(group A : 5 male, 10 female, 44.4+/-7.7 years), 15 hypertensives without LVH(group B : 5 male, 10 female, 45.5+/-8.6 years), 85 hypertensives with DST(group C : 9 male, 16 female, 47.5+/-8.6 years) and 15 hypertensives with concentric LVH(group D : 8 male, 7 female, 47.7+/-6.1 years). The obtained results were as follows : 1) Left ventricular ejection fraction was 71.6+/-6.3% in group A, 71.9+/-7.5% in group B, 731+/-7.0% in group C, and 70.3+/-10.3% in group D. Ejection fraction was not significantly different in each other group. 2) Left ventricular mass index(LVMI) by echocardiogram was 87.8+/-20.6g/m

Two factors of the ventricular function, systolic contractile and diastolic relaxing functions, cooporate in pumping the adequate blood volumes to suffice bodily demands. In some hypertensive patients with marked left ventricular hypertrophy, the intact systolic function of the ventricle associated with clinical symptom of congestive heart failure(CHF), which is considered to be a consequence of diastolic dysfunction. In this study 10 hypertensive patients(group A) complaining of exertional dyspnea or chest pain with increased left ventricular mass index and normal systolic function and 6 normotensive controls(group B) were examined by cardiac catheterization and echocardiography to assess the left ventricular systolic and diastolic function and ventricular responses to constant infusion of nitroprusside. Various systolic and diastolic function indices were measured by cardiac catheterization and echocardiography. 1) The ejection fraction(EF), fractional fiber shortening, mean velocity of circumferential fiber shortening, left ventricular(LV) peak+dp/dt, change of slope of LV peak systolic pressure-volume and pressure-dimension relations in group A were not different from those of group B in the resting states. 2) Diastolic dysfunction was evidenced by prolonged A2D time, decreased OR slope, decreased peak negative dp/dt and increased diastolic time constant 'T' in group A. 3) Cardiac index by thermodilution method was negatively related to left ventricular mass index(LVMI) measured by echocardiography, whereas time constant T was positively related to LVMI. 4) With constant infusion of nitroprusside, LV systolic pressure, LV end-diastolic pressure and pulmonary arterial pressure were decreased, and left ventricular end-systolic stress and stroke work index(SWI) derived from left ventricular pressure-volume loop area were decreased, EF was increased, but time constant T was prolonged and cardiac output(CO) by thermodilution method was decreased in group A. 5) In group B, with constant infusion of nitroprusside, EF, SWI and CO were pratically unaffected and time constant T was not prolonged significantly. These reults suggest that patients with hypertensive hypertrophic left ventricle is associated with diastolic dysfunction, which could further be exacerbated by a vasodilator such as nitroprusside.

Cardiac output depends on the ability of systolic ejection and diastolic filling of the heart. M-mode echocardiography can provide accurate clinical assessment of left ventricular systolic and diastolic functions. To see whether there are changes of the left ventricular function in asymptomatic hypertensives and if any kind of dysfunction and whether any relationship between the pattern of the ventricular hypertrophy and type of ventricular dysfunction exists, the authors examined the systolic and diastolic function indices of the left ventricle in 50 normotensives and 88 hypertensives composed of 18 patients without left ventricular hypertrophy(group 1), 40 patients with disproportionate septal thickening (group 2) and 30 patients with concentric left ventricular hypertrophy(group 3). Obtained results were as follows : 1) Blood pressure & left ventricular mass index were increased significantly in each hypertensive group compared to normal control. 2) Ejection fraction & fractional shortening in the hypertensive groups were not different from the normotensive control group. 3) Left ventricular isovolumic relaxation time(A2D time) was prolonged in each hypertensive group, especially in group 3. 4) Left atrial emptying index (AEI) was decreased in each hypertensive group. 5) Left ventricular percent ventricular A wave (% VAW) was increased in all hypertensive groups. Above study suggested that the left ventricular diastolic function could be impaired in the hypertensives without associated systolic dysfunction, and the degree of the diastolic dysfunction was not much affected by the type of left ventricular hypertrophy, but the more prolonged A2D time in the concentric hypertrophy group.

Objective To investigate the clinical outcomes of an invasive strategy for elderly (aged≥75 years) patients with acute ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS). Methods Data on 366 of 409 elderly CS patients from a total of 6,132 acute STEMI cases enrolled in the Korea Acute Myocardial Infarction Registry between January 2008 and June 2011, were collected and analyzed. In-hospital deaths and the 1-month and 1-year survival rates free from major adverse cardiac events (MACE;defined as all cause death, myocardial infarction, and target vessel revascularization) were reported for the patients who had undergone invasive (n=310) and conservative (n=56) treatment strategies. Results The baseline clinical characteristics were not significantly different between the two groups. There were fewer in-hospital deaths in the invasive treatment strategy group (23.5%vs. 46.4%, P＜0.001). In addition, the 1-year MACE-free survival rate after invasive treatment was significantly lower compared with the conservative treatment (51%vs. 66%, P=0.001). Conclusions In elderly patients with acute STEMI complicated by CS, the outcomes of invasive strategy are similar to those in younger patients at the 1-year follow-up.
