“…Anatomic studies have suggested that precordial ST-segment depression correlated with the presence of extensive inferior or additional "true posterior" necrosis. [16][17][18] More recent radionuclide imaging studies have suggested the presence of either predominant posterolateral myocardial infarction, associated anterior ischemia,s,6 or involvement of the inferoseptal wall. 4 A recent report indicates that early anterior ST depression, a common phenomenon, was neither highly specific nor sensitive for posterior wall infar~tion.~ The specificity for posterior myocardial infarction increases if the anterior ST depression remained for 72 hours.3 The genesis of anterior ST depression was not addressed in our study.…”

Summary:In 229 patients admitted to the coronary care unit (CCU) at Sahlgren's Hospital developing inferior myocardial infarction, and with no previous myocardial infarction, the clinical outcome was related to the presence of ST-segment depression in 16 anterior chest leads. In all, 64% had anterior ST-segment depression. These patients differed from those not having ST depression in several aspects. They had larger infarcts, as assessed by serum enzyme activity and ECG recording. They were more prone to congestive heart failure and required more treatment for this complication. Their intensity and duration of pain during the first 4 days appeared to be more substantial. During a 5-year follow-up, patients with anterior ST depression tended to have a higher mortality. We conclude that among patients with inferior myocardial infarction and no previous infarction, those with anterior ST-segment depression form a subgroup with a more severe clinical course.

“…Evidence of myocardial infarction (13–16) was either clearly apparent or strongly suggested in 38 per cent of the 90+ age group. The number of additional cases that may have been present but masked by conduction disturbances is conjectural.…”

The electrocardiograms of 100 men and women, all past the age of 90, were analyzed for conduction times, axis deviation, summed frontal QRS and T amplitudes. The ECG patterns were classified, and limited clinical correlations were made. The heart rate, R‐T and QRS intervals remained virtually unchanged with age. An increase in PR intervals, a left axis shift and a reduction in summed frontal T values were noted. The high incidences of atrial fibrillation, left anterior hemiblock, extra systoles and delayed AV conduction were probably a result of the widespread use of digitalis. The two most common ECG abnormalities were left ventricular hypertrophy (evidently a natural consequence of advanced age) and myocardial infarction (often undiagnosed clinically).

It has been hypothesized that Helicobacter pylori (Hp) infection may contribute to reduced stature, risk of hypertension or obesity. The aim was to evaluate body indices in Hp positive and negative persons. A total of 2436 subjects (4-100 years old) were tested for Hp status by 13 C-urea breath test. Data on height and weight were collected for 84%, and blood pressure for 80% of the study subjects. The prevalence of Hp infection was 41.6%. The odds ratio for a 10-year increase in age was 1.21 (95% CI 1.17-1.25, p-value <0.001). Statistically significant negative association of Hp positivity with body height was most pronounced in the younger age groups, while a positive association of Hp positivity with body mass index was only seen in those aged 15+ years. There was a negative effect of Hp positivity on systolic and diastolic blood pressure in subjects below 25 and a relatively strong positive effect on blood pressure in subjects over 65 years. Residual confounding by social characteristics as a possible explanation for the associations of Hp positivity with height and blood pressure cannot be excluded. Unmeasured factors related to social and family environment may cause the apparent association between Hp positivity and children's growth and blood pressure.
