This study evaluated normotensive diabetic patients' blood pressure response to graded exercise and their echocardiographic pattern of left ventricular geometry.
A descriptive, cross-sectional, hospital-based study was carried out on 30 normotensive type 2 diabetic patients and 34 controls, aged 30 to 60 years. The outcome measures were to determin...

... capacity in G2 subjects was significantly lower than in G1 by 12.94% (7.4 ± 1.1 vs 8.5 ± 1.5 METs; p = 0.042). Although, there was no statistically significant difference between the LV mass index in the two groups, G2 subjects had significantly higher relative wall thicknesses than those in G1 (0.53 ± 0.03 vs 0.41 ± 0.04; p < 0.001) (Table 4). ...

The aims of this study were to establish a reliable model of chronic mitral regurgitation (MR) in rats and verify the pathophysiological features of this model by evaluating cardiac function using serial echocardiography and a pressure-volume analysis.
MR was created in 37 Sprague-Dawley rats by making a hole with a 23 gauge needle on the mitral le...
Background: The primary cause of ischemic heart failure (HF) is myocardial infarction (MI) resulting in left ventricle (LV) wall motion abnormality secondary to ventricular remodeling. A prospective, nonrandomized study conducted in China was designed to assess safety and efficacy of the percutaneous ventricular restoration therapy using Parachute...
It is debated whether subjects with concentric remodeling (CR, normal left ventricular mass index (LVMI) and increased relative wall thickness (RWT)) are at higher cardiovascular risk than those with normal geometry (NG, normal LVMI and RWT). The aim of this study was to perform a meta-analysis of studies evaluating cardiovascular events in subject...
Left ventricular remodeling results in cardiac dysfunction and accounts for the majority of the morbidity and mortality following myocardial infarction (MI). The aim of the present study was to investigate the effect of asiatic acid (AA) on cardiac function and left ventricular remodeling in a rat model of MI and explore the underlying mechanisms....
Injectable biomaterials are an attractive therapy to attenuate left ventricular (LV) remodeling after myocardial infarction (MI). Although studies have shown that injectable hydrogels improve cardiac structure and function in vivo, temporal changes in infarct material properties after treatment have not been assessed.

... Interestingly, young adults with a genetically increased risk of future hypertension have higher LVM that is not fully explained by resting SBP [1]. These associations show the importance of answering the following question: does eSBP predict LVM? Prior research examining the relationship between eSBP and LVM has primarily found a direct association between these variables [12,16,[25][26][27][28][29][30][31][32][33][34][35][36][37][38], but this is not a universal finding [12,27,28,30,39,40]. When examining the results that do not support the association between eSBP and LVM, the participants did not habitually exercise [12,27,28,30,39,40]. ...
Exercise is a major modifiable lifestyle factor that leads to temporarily increased systolic blood pressure (SBP), which is thought to influence left ventricular mass normalized to body surface area (LVM/BSA). This relationship has never been studied in women who habitually perform resistance exercise. Purpose: To determine if a direct correlation exists between the SBP response to resistance exercise (change from rest; eSBP) and LVM/BSA in young healthy women who habitually resistance train. Methods: Leg extension resistance exercise was performed while continuously monitoring blood pressure using finger plethysmography. LVM was estimated using echocardiography. Data are shown as mean ± SD. Results: Thirty-one women participated (age 23 ± 3 years, height 164 ± 7 cm, body mass 63.7 ± 10.3 kg). Resting SBP (110 ± 8 mmHg, r = 0.355, p = 0.049) was shown to be directly correlated to LVM/BSA (72.0 ± 28.4 g/m2). Conversely, eSBP (30.8 ± 14.6 ∆mmHg, r = −0.437, p = 0.014) was inversely related to LVM/BSA. eSBP was not correlated to interventricular septum width (0.88 ± 0.12 cm, r = −0.137, p = 0.463) or posterior wall thickness (0.91 ± 0.15 cm, r = −0.084, p = 0.654). eSBP was inversely related to left ventricle internal diameter during diastole (LVIDd) (4.25 ± 0.33 cm, r = −0.411, p = 0.021). Conclusion: Counter to the hypothesis, these data suggest an inverse association between eSBP during resistance exercise and LVM/BSA in healthy young women who resistance train. This relationship is due to a smaller LVIDd with greater eSBP.
Purpose:
Arterial hypertension (aHT) is the leading risk factor for morbidity and mortality worldwide. Blood pressure (BP) deviation at rest is well defined and accompanies risk for cardiovascular events and cardiovascular mortality. A growing body of evidence emphasises that an exaggerated blood pressure response (EBPR) in cardiopulmonary exercise testing (CPET) could help to identify seemingly cardiovascular healthy and normotensive subjects, who have an increased risk of developing aHT and cardiovascular events in the future.
Materials and methods:
The PubMed online database was searched for published studies reporting exercise-related BP and both the risk of aHT and cardiovascular events in the future.
Results:
We identified 18 original studies about EBPR in CPET, which included a total of 35,151 normotensive individuals for prediction of new onset of aHT in the future and 11 original studies with 43,012 enrolled subjects with the endpoint of cardiovascular events in the future. Although an EBPR under CPET is not well defined, a large number of studies emphasise that EBPR in CPET is associated with both new-onset aHT and cardiovascular events in the future.
Conclusions:
A growing number of studies support the hypothesis that EBPR in CPET may be a diagnostic tool to identify subjects with an elevated risk of developing aHT and cardiovascular events in the future.
